Why This Checklist Matters

Feeling low sometimes is a universal human experience. Grief, stress, life transitions — all of these can pull our mood downward for days or even weeks. But there's an important difference between a rough patch and something that genuinely needs clinical support. Understanding that distinction can feel confusing, especially from the inside.

This checklist is designed as a gentle self-reflection tool. It draws on criteria used by mental health professionals — including those described in the DSM-5 — to help you notice patterns worth discussing with a qualified clinician. For a deeper look at how everyday low mood differs from clinical depression, see our article on the difference between a low mood and clinical depression.

This checklist is for informational and self-reflection purposes only. It is not a diagnostic tool and does not replace evaluation by a licensed healthcare professional.

If You're Having Thoughts of Self-Harm

If you are experiencing thoughts of suicide or self-harm, please seek help immediately. In the United States, you can call or text 988 to reach the Suicide and Crisis Lifeline, available 24 hours a day, seven days a week. If you are in immediate danger, call 911 or go to your nearest emergency room. You do not have to manage this alone.

What to Look For: The Checklist

Work through the items below honestly. If several of these signs resonate — particularly those marked as high priority — consider scheduling a conversation with your primary care provider or a mental health professional. You don't need to check every box to seek help. One persistent, distressing symptom is already a valid reason to reach out.

Duration and Persistence

Notice whether your low mood has lasted most of the day, nearly every day, for two weeks or longer. Must
Check whether the low mood returns repeatedly over months, even if it lifts temporarily. Must
Observe if you've stopped expecting to feel better, as if a return to your usual self feels impossible. Should

Impact on Daily Functioning

Assess whether low mood is affecting your ability to perform at work, school, or in caregiving responsibilities. Must
Consider whether social withdrawal has become a pattern — avoiding friends, family, or activities you used to enjoy. Must
Ask yourself whether basic self-care tasks — bathing, eating regular meals, keeping appointments — have become difficult to maintain. Should
Reflect on whether relationships have suffered due to irritability, emotional distance, or persistent sadness. Should

Emotional and Cognitive Signs

Take note if you feel a persistent sense of worthlessness, guilt, or hopelessness that doesn't ease with reassurance. Must
Notice whether you've lost interest or pleasure in activities — hobbies, food, socializing — that used to matter to you. Must
Observe whether concentration, memory, or decision-making have noticeably declined without a clear external reason. Should
Check for a persistent negative inner narrative — a sense that things are bad and won't improve. Should

Physical Warning Signs

Identify whether sleep has changed significantly — either sleeping far more than usual or struggling with insomnia most nights. Should
Consider whether your appetite has shifted noticeably — eating much more or much less than usual without intentional dieting. Should
Notice if you're experiencing unexplained fatigue or a heavy, slowed feeling in your body most days. Should
Reflect on whether unexplained physical symptoms — headaches, digestive issues, body pain — have emerged or worsened alongside your mood. Nice to have

Urgent Signs Requiring Immediate Support

Seek help immediately if you are experiencing thoughts of suicide, self-harm, or feeling that others would be better off without you. Must
Contact a crisis line or emergency services right away if these thoughts include a plan or feel urgent — do not wait. Must
Reach out to a trusted person today if you've been using alcohol or substances more heavily to manage your mood. Must

Keep in mind that some of these experiences — particularly physical ones like fatigue, appetite shifts, and disrupted sleep — are also associated with medical conditions unrelated to depression. Our article on the physical side of depression explains the body-mind connection in more depth. A clinician can help rule out other causes.

What to Do With Your Answers

If you recognized yourself in several of these signs, the most important step is to tell someone who can help. That might be your primary care physician, a licensed therapist, or a psychiatrist. If you're unsure where to start, a visit to your regular doctor is always a reasonable first step — they can assess your symptoms, rule out physical causes, and refer you onward if needed. Our hub on seeing a doctor offers practical guidance on navigating that process.

Don't Wait Until It Feels Severe Enough

A common barrier to seeking help is the belief that your symptoms aren't 'bad enough' to deserve professional attention. Mental health care is not reserved for crisis situations. Addressing low mood early — before it deepens or disrupts more areas of your life — tends to lead to better outcomes, according to research published by the National Institute of Mental Health. If something feels persistently wrong, that is sufficient reason to make an appointment.

If you're concerned about someone else who shows these signs, you don't have to navigate that alone either. Our guide on talking to someone you love about their depression walks through how to start that conversation with care. And if anxiety is part of the picture — for you or for them — our article on when to seek professional help for anxiety covers overlapping warning signs worth knowing.
