Am I Depressed? How to Tell and What to Do Next

Maybe what you’re feeling is less like sadness and more like flatness, exhaustion that sleep doesn’t fix, or a short fuse you don’t recognize in yourself. You keep wondering whether it’s “real” depression or just a rough patch, and that uncertainty can keep you stuck for a long time.

Your mood normally rises and falls with what happens to you, and then it recovers. Depression is different because it settles in and spreads, changing sleep, appetite, energy, focus, and how you see yourself. Telling the two apart takes precision, because clinicians look at a specific set of symptoms, how long they’ve lasted, and how much they get in the way.

The usual first step is a short questionnaire called the PHQ-9, which asks how often you’ve had each of nine core depression symptoms over the past two weeks. It has a strong track record. In a BMJ screening meta-analysis pooling data from 58 studies, a score of 10 or higher correctly flagged 88% of people with major depression and correctly cleared 85% of people without it, when checked against clinician-led interviews. The results are real, and the science is well established.

But a score can’t tell you what your symptoms mean in your life, and at Siggy we think the questions behind the number matter as much as the number itself.

That’s why this guide walks through the same three questions a clinician asks, about which symptoms you have, how long they’ve lasted, and how much they affect your life, along with the signs that often get missed. It covers the same ground a screening score does, with more precision, because it explains why depression can look like irritability, aches, or numbness instead of tears. That approach comes from research on how depression actually shows up, and it changes how depression gets recognized.

Is It Depression or a Rough Patch?

Everyone has low stretches. What separates depression is a combination of time, number of symptoms, and impact. Under the APA diagnostic criteria, major depression means five or more of nine symptoms during the same two-week period, most of them present nearly every day, with at least one being low mood or loss of interest or pleasure. The symptoms also have to cause real distress or get in the way of daily life. The PHQ-9 questionnaire uses a looser screening rule, counting a symptom if it shows up more than half the days and counting thoughts of death or self-harm whenever they occur, so it casts a wider net than the diagnosis itself. In the PHQ-9 validation study, as scores rose, people’s day-to-day functioning dropped, and their sick days and medical visits went up.

Depression is also common. In a U.S. national survey of 36,309 adults, 10.4% had major depression in the past year and 20.6% had it at some point in their lives. Odds were higher for women, and about three times higher for adults ages 18 to 29 compared with older adults.

What Symptoms Do Clinicians Look For?

The two core symptoms are feeling down, depressed, or hopeless, and losing interest or pleasure in things you usually enjoy. You need at least one of them. The other seven cover how depression spreads through the rest of your life: sleeping too much or too little, feeling tired or low on energy, eating much more or less than usual, feeling worthless or guilty, trouble concentrating, moving or speaking more slowly or feeling restless, and thoughts that you’d be better off dead or of hurting yourself.

That last symptom matters most of all. If you’re having thoughts of suicide or self-harm, call or text 988 now, or call 911 if you’re in danger. You don’t need to meet any other criteria to deserve help today.

Can Depression Look Like Something Other Than Sadness?

It often does. In a 14-country depression study in primary care, 69% of patients with major depression reported only physical symptoms, such as headaches, back pain, or weakness, and 11% denied emotional symptoms when asked directly. Physical presentations were more common where people didn’t have an ongoing relationship with a primary care doctor.

Irritability is another disguise. In a long-term NIMH study of 536 people in a depressive episode, 54.5% showed overt irritability or anger, and it was linked to more severe and longer-lasting depression. Depression also varies from person to person. A STAR*D symptom analysis found 1,030 different symptom combinations among 3,703 people with depression, and the most common combination described only 1.8% of them. Our guide to what depression feels like goes deeper on the emotional, physical, and thinking sides.

Here’s how often these less obvious patterns showed up in research.

Pattern	What the Research Found	Study Type
Mostly physical symptoms	69% reported only physical symptoms	14-country primary care study
Denying low mood	11% denied emotional symptoms when asked	Same 14-country study
Irritability or anger	Present in 54.5% during an episode	Long-term NIMH cohort
Unique symptom mix	1,030 combinations among 3,703 patients	Analysis of a large trial

Each row comes from the studies linked just above.

Could It Be Grief Instead?

Sometimes what feels like depression is grief, and the two share a lot, including sadness, poor sleep, and trouble concentrating. In the U.S. national survey, 12.9% of people who’d had major depression had episodes only right after the death of someone close, and those episodes lasted less than two months.

Grief still deserves attention. If low mood after a loss isn’t easing over time, or it comes with hopelessness, harsh self-blame, or thoughts of death, it’s worth talking with a clinician. Our guide to grief versus depression explains the overlap.

What Does a Depression Screening Score Mean?

The PHQ-9 adds up how often you’ve had each symptom, from 0 to 27. The validation study described scores of 5, 10, 15, and 20 as mild, moderate, moderately severe, and severe, and found that a score of 10 or higher had 88% sensitivity and 88% specificity for major depression. You can take the questionnaire in our depression test.

A screen is a starting point rather than a diagnosis. In the validation sample, where about 7% of people had major depression, only 31% to 51% of those who screened positive actually had it, depending on the cutoff. The authors note that a screen’s predictive value depends on how common depression is in the group being screened, which is why a clinician needs to look at the whole picture.

Screening is worth doing anyway. In its 2023 recommendation statement, the U.S. Preventive Services Task Force recommends depression screening for all adults, including pregnant and postpartum people and older adults.

What Should You Do If You Think You’re Depressed?

Start small, and don’t wait for things to get worse:

1. Notice what’s been happening over the past two weeks, including sleep, energy, appetite, focus, and interest.
2. Take a validated screen like the PHQ-9 and note your score.
3. Talk with a clinician about what you’ve found, even if you’re not sure it counts.
4. If you have thoughts of suicide, call or text 988, or call 911 in an emergency.

Waiting is common, and it’s costly. In a national treatment-delay study, people with mood disorders who eventually sought care typically waited 6 to 8 years after symptoms first began. The national survey found that almost 70% of people with lifetime major depression had received some treatment, which also means a substantial minority never did.

Treatment works for many people. In a 2018 Lancet network meta-analysis of 522 trials with 116,477 participants, all 21 antidepressants studied were more effective than placebo for major depression. Talk therapy is another evidence-based path, and our guide to medication versus therapy for depression compares the two.

How Siggy Fits In

Siggy’s licensed prescribers diagnose and treat the full range of mental health conditions, including depression. Siggy’s intake is a structured way to put what you’re feeling into words rather than a diagnosis, and it includes a standard depression questionnaire. A licensed prescriber reviews your results and your full intake before making a diagnosis or prescribing anything.

The anonymous intake asks for no name, email, or account, which can make it easier to be honest about symptoms you haven’t told anyone about. You’ll get a downloadable summary to keep or share with any clinician, so you don’t have to retell your story from scratch.

Siggy isn’t an emergency service. If you’re in crisis, call 911 or call or text 988. This article is for education only and isn’t a substitute for personal medical advice. It reflects sources available as of October 2026.

The Bottom Line on Whether You’re Depressed

Depression is a cluster of symptoms that lasts at least two weeks, includes low mood or lost interest, and gets in the way of your life, which is what sets it apart from an ordinary bad week. It doesn’t always look like sadness, either. A screening score is a useful first step, and a clinician can confirm what’s going on. If your symptoms seem to hide behind exhaustion or a short temper, our guide to high-functioning depression may sound familiar.

Start Your Anonymous Intake

If you’re in crisis right now, call 911 or call or text 988 first. If you’ve been asking yourself “am I depressed?” for weeks and want a clearer answer, start your anonymous intake. It’s free, there’s no name or email required, and a licensed prescriber reviews your intake before anything is prescribed. You’ll leave with a summary of what you shared, ready for whoever helps you next.
