Depression: a guide to symptoms, types and treatment

What depression looks like, the main types, when to get evaluated, and how depression treatment works at ANK, by secure video across New Jersey.

Quick answer

Everyone feels low sometimes. Depression is different: it lasts at least 2 weeks, shows up most of the day, nearly every day, and changes how you feel, think, sleep, eat and work. It's one of the most common mental health conditions in the United States, and it comes in several forms, from major depression to long-lasting, seasonal and hormone-related depression. It's treatable, usually with therapy, medication, or both. This guide explains what depression looks like, the main types, when it's worth getting evaluated, and what care with us looks like.

Key takeaways

  • Depression is more than sadness: it lasts at least 2 weeks, is there most of the day, nearly every day, and gets in the way of daily life.
  • It comes in several forms: major depression, persistent depression, seasonal depression, and depression tied to pregnancy, the menstrual cycle or perimenopause. Low periods can also be part of bipolar disorder, which is treated differently.
  • Therapy and medication both help, and they're often used together. Antidepressants usually take 4 to 8 weeks to work.
  • A careful evaluation sorts out which pattern fits, and checks for things that can look like depression, such as burnout or a thyroid problem.

What depression looks like day to day

Everyone feels sad or low sometimes, and those feelings usually pass. Depression lasts longer and runs deeper. It can affect how you feel, how you think, and how you handle everyday things like sleeping, eating or working.

It doesn't always look like sadness. It can show up as irritability or anger, feeling detached, drinking more, or physical problems such as aches, headaches or stomach trouble without a clear cause.

Common signs, in plain language

  • A sad, anxious or "empty" mood that doesn't lift
  • Losing interest or pleasure in things you used to enjoy
  • Low energy, or feeling slowed down
  • Trouble concentrating, remembering or making decisions
  • Changes in sleep or appetite
  • Feeling hopeless, guilty or worthless
  • Thoughts of death or suicide

These signs are a general guide, not a checklist for diagnosis. Not everyone has all of them.

Sadness, a rough patch, or depression?

Feeling sad after a loss, a disappointment or a hard stretch is part of life, and it usually eases with time, rest or support. Depression lasts longer and runs deeper: it's there most of the day, nearly every day, for at least 2 weeks, and it starts to get in the way of work, relationships and everyday tasks.

The main types, in plain words

What causes depression?

There's rarely one cause. Research suggests a mix of genetic, biological, environmental and psychological factors plays a role. A few things that matter:

  • Family history: depression can run in families.
  • Life events: loss, stress, trauma and major changes can bring it on, though it can also appear without an obvious reason.
  • Physical health: depression often comes with chronic illnesses such as diabetes, cancer, heart disease and chronic pain, and some medical conditions and medications can cause similar symptoms.
  • Past depression: people who have had depression are more likely to have it again, which is one reason regular follow-ups matter.

Depression isn't a weakness or something you can simply snap out of. It's a recognized condition, and it responds to treatment.

Depression in different parts of life

When it's worth getting evaluated

It's worth reaching out if:

  • Low mood, emptiness or loss of interest has lasted more than 2 weeks
  • It's affecting your sleep, work, school or relationships
  • Everyday tasks take far more effort than they used to
  • You're relying on alcohol or other substances to get through
  • You've tried to manage it on your own and it isn't enough
  • Depression has come back after getting better before

You don't need to wait until things are at their worst. If you've been looking for a psychiatrist for depression treatment in New Jersey, our board-certified psychiatric nurse practitioners can evaluate what's going on and talk through your options.

If you're in crisis or thinking about harming yourself, call or text 988 (Suicide & Crisis Lifeline), any time, day or night. In an emergency, call 911 or go to the nearest emergency room.

What an evaluation at ANK looks like

There's no blood test for depression. A careful evaluation looks at the pattern, not just how you feel today, and we take the time to hear it:

  • When your symptoms started, how long they've lasted and whether they've come back before
  • Whether they follow the seasons, your menstrual cycle, pregnancy or perimenopause
  • Any past periods of unusually high energy or little need for sleep, which can point to bipolar disorder
  • How much of it is tied to work stress
  • Your physical health and medications, since some medical conditions, such as thyroid problems, and some medications can cause similar symptoms. Sometimes that means checking in with your primary care provider.
  • Conditions that often come with depression, such as anxiety, or alcohol and substance use
  • Past treatment, and what did or didn't help

This is part of a comprehensive psychiatric evaluation. Your first evaluation is up to 90 minutes in length. Some people need more time, some less, and we take the time you need. Follow-up visits are typically 20 to 30 minutes, and extended follow-ups are available. You'll leave understanding what we think is going on, and why. Read the questions you'll be asked at a first psychiatric evaluation.

Treatment options

Depression is treatable. Treatment usually involves therapy, medication, or both, chosen around your needs, preferences and health. For milder depression, therapy is often tried first. For moderate or severe depression, medication is usually part of the plan from the start, and many people use both.

Therapy

Talk therapy, such as cognitive behavioral therapy (CBT), helps with depression by working on the thoughts, habits and routines that keep it going. Depending on your clinician, visits may draw on supportive, motivational interviewing, CBT-based, or DBT-based skills. We don't offer standalone weekly therapy, but we're happy to help you find a therapist and, with your permission, we'll coordinate with them.

Medication

Antidepressants are the medications most often used. They usually take 4 to 8 weeks to work. Because they can trigger mania or hypomania, we check for bipolar disorder before starting one. Finding the best option can take some trial and error, so we go step by step and explain the reasons behind each choice. The medication quick facts below list the FDA-approved options. Our major depressive disorder page explains how long treatment usually lasts, and what happens when the first medication isn't enough.

Everyday steps that help

We also talk through the basics that support recovery: a regular bedtime and wake-up time, physical activity, regular meals, and staying connected with people you trust. Regular follow-ups are how we keep your plan on track and adjust it as things change.

Insurance and cost

We're in network with Horizon BCBS NJ and most other BCBS plans, Aetna, Cigna, UHC, Optum, Oscar, Oxford and Curative. Coverage can vary by plan and by provider, so after you submit your intake packet, we'll verify your benefits and let you know what to expect before your first appointment. We don't accept Medicare or Medicaid (NJ FamilyCare). Because of Medicare and Medicaid rules, we also can't see patients with these plans on a private-pay basis.

Self-pay rates, superbills and the Good Faith Estimate are on our insurance and fees page.

Medication quick facts

FDA-approved medications for depression include

These are some of the medications FDA-approved for depression. Most are approved for major depressive disorder; bupropion extended-release is also approved to prevent seasonal depressive episodes. FDA approval reflects which uses a manufacturer chose to study and submit, not the only medications that help. For medications used off-label, see our pages on major depressive disorder and persistent depressive disorder. Our seasonal affective disorder page covers other antidepressants used for the seasonal pattern. Your provider will talk with you about what fits you. There are more than these cards can hold, so the rest are listed below the cards.

Browse by name. Your provider will talk with you about which options fit you.

SSRIs
SNRIs
Other antidepressants
Add-on options

Sertraline (Zoloft)

An SSRI antidepressant (selective serotonin reuptake inhibitor)

FDA-approved for
Major depressive disorder. Also OCD, panic disorder, PTSD, social anxiety disorder and PMDD.
Common side effects
Nausea, diarrhea, tremor, indigestion, less appetite, sweating and sexual side effects.
Antidepressant warning
In short-term studies, antidepressants increased suicidal thoughts and behaviors in people up to age 24. Anyone taking one should be watched closely for worsening, especially during the first few months and at times of dosage changes. Don't stop suddenly; talk with your provider first.

General information, not medical advice; talk with your provider.

Also FDA-approved for depression: other forms of venlafaxine (immediate-release) and bupropion (Wellbutrin SR, Aplenzin, Forfivo XL); olanzapine and fluoxetine for depression that hasn't responded to two antidepressants; the older tricyclic antidepressants amitriptyline, nortriptyline, imipramine, desipramine, doxepin, protriptyline, trimipramine and amoxapine; the MAO inhibitors phenelzine (Nardil), tranylcypromine (Parnate), isocarboxazid (Marplan) and the selegiline patch (Emsam); and nefazodone, which carries a warning about liver failure. These are used less often today, usually when newer medications haven't helped. Links go to each FDA label.

Esketamine (Spravato), a nasal spray, is also FDA-approved for treatment-resistant depression, on its own or with an oral antidepressant, and, alongside an oral antidepressant, for depression in adults with acute suicidal thoughts or actions. It's a controlled medication given only in certified treatment centers, with monitoring for at least 2 hours afterward, so it isn't prescribed for home use. We can talk about whether a referral makes sense. (FDA label)

Brand names are listed for recognition only. Antidepressant labels warn that they can trigger mania or hypomania, and ask providers to check for bipolar disorder first. Most can also cause serotonin syndrome when combined with other medications that raise serotonin, and many raise bleeding risk with aspirin, NSAIDs (such as ibuprofen) or blood thinners, so tell your provider everything you take. Antipsychotics carry a warning about older adults with dementia, which mainly concerns people older than the adults we see.

Frequently asked questions

Is depression the same as sadness?

No. Sadness usually passes. Depression lasts longer, most of the day, nearly every day, for at least 2 weeks, and it gets in the way of daily life.

Do I need to know which type of depression I have before my visit?

No. Many people come in unsure. We look at how long your symptoms have lasted, whether they follow a pattern such as the seasons or your cycle, and whether you've had high periods too. Sorting that out is part of the evaluation.

Will I need medication?

Not necessarily. Therapy, medication, or both can help, and the choice is yours. If medication could help, your provider will explain the options, side effects and what to expect so you can decide together.

How long do antidepressants take to work?

Usually 4 to 8 weeks. Sleep, appetite and concentration often improve before mood lifts, so it's worth giving a medication a fair chance.

Do I need therapy too?

It depends. For milder depression, therapy is often tried first. For moderate or severe depression, medication is usually part of the plan from the start, and many people use both. We don't offer standalone weekly therapy, but we're happy to help you find a therapist and, with your permission, we'll coordinate with them.

Can you help with postpartum, PMDD or perimenopausal depression?

Yes. These are part of our women's mental health care.
