The WHO states the following:
“Psychological treatments are the first treatments for depression. They can be combined with antidepressant medications in moderate and severe depression. Antidepressant medications are not needed for mild depression.”
While only a qualified healthcare professional can make the final call, here are the main red flags according to the current research and clinical guidelines (APA, NICE, WHO):
- Persistent, intense symptoms for weeks or months
-
- Feeling sad, hopeless, or emotionally numb nearly every day for at least two weeks.
-
- Loss of interest in activities you used to enjoy (anhedonia).
-
- Symptoms aren’t just occasional dips; they’re constant or worsening.
- Functional impairment
-
- Difficulty performing at work, managing studies, or handling daily tasks.
-
- Struggling to maintain relationships because of withdrawal or irritability.
-
- Even basic self-care (showering, cooking, paying bills) feels tremendous.
- Physical and cognitive changes
-
- Major changes in sleep (too much or too little) and appetite (weight gain or loss).
-
- Noticeable drop in concentration, memory, and decision-making abilities.
-
- Fatigue that doesn’t go away with rest.
- Suicidal thoughts or self-harm urges
-
- Thinking about death or suicide, making plans, or engaging in self-harm.
-
- This is an immediate sign to seek help, and antidepressants may be part of an urgent treatment plan.
- No improvement from non-medication approaches
-
- You’ve tried therapy, exercise, sleep hygiene, social support, and stress management consistently for several weeks or months, but symptoms remain severe.
- Recurrent depression history
-
- Multiple past depressive episodes, especially if they were severe or hard to treat.
-
- Antidepressants can help prevent relapses in such cases.
- Co-occurring anxiety or chronic pain
-
- Antidepressants may target both sets of symptoms when depression is accompanied by severe anxiety disorders, panic attacks, or certain chronic pain syndromes.
- Emotional reactivity is blunted
-
- You’re not just sad because you can’t feel much at all, even during events that should make you happy or upset.
-
- This emotional flattening can be a sign of severe or treatment-resistant depression.
- Persistent guilt or self-blame
-
- Constantly feeling worthless, guilty, or like a burden without a rational explanation.
-
- These thoughts are intense and hard to challenge, even in therapy.
- Physical pain without a clear cause
-
- Headaches, digestive issues, back pain, or muscle aches that persist despite medical evaluation.
-
- Depression can amplify pain perception via changes in serotonin and norepinephrine pathways, both targets of antidepressants.
- Irritability and anger outbursts
-
- Depression shows up as agitation, frustration, or hostility rather than low mood for some people.
- Feeling slowed down/psychomotor retardation
-
- Moving, speaking, or even thinking feels physically slower.
-
- This is a serious symptom that often requires medical intervention.
- Cognitive fog that won’t lift
-
- Trouble focusing, remembering things, or making decisions even on “good days.”
-
- Sometimes the cognitive symptoms remain even when the mood is only mildly low.
- Morning worsening
-
- Symptoms are noticeably worse in the morning and may ease slightly later in the day.
-
- This circadian variation is a marker of biological depression, often responsive to medication.
- Loss of motivation despite clear goals
-
- You want to get better or achieve something, but feel like an invisible wall is stopping you.
-
- The lack of drive persists even with strong willpower and external pressure.
- Seasonal or postpartum patterns
-
- Symptoms appear every winter (seasonal affective disorder) or after childbirth (postpartum depression) and are intense enough to disrupt functioning.
- Repeated relapse after stopping medication
-
- It’s a strong sign you may need longer-term treatment if you’ve improved on antidepressants but symptoms return after discontinuation.
- Sudden loss of emotional resilience
-
- Small stressors that you used to handle now completely engulf you.
-
- This “fragility” can be a sign that your brain’s stress-regulation systems are depleted.
- Feeling detached from reality or yourself
-
- Episodes of depersonalization (“I don’t feel like myself”) or derealization (“The world feels unreal”).
-
- These can be linked to severe depression and anxiety when persistent.
- Changes in speech and language
-
- Speaking less, using shorter sentences, or having long pauses because finding words feels hard.
-
- Clinicians sometimes note this as part of psychomotor slowing.
- Persistent hopelessness about the future
-
- Not just pessimism but an unshakable conviction that things will never improve, even when there’s no evidence for it.
-
- This mindset strongly predicts poor recovery without treatment.
- Loss of the ability to feel comforted
-
- Support from friends or family doesn’t lift your mood at all.
-
- In normal sadness, reassurance usually helps at least a little.
- Worsening of other health conditions
-
- Chronic illnesses (diabetes, heart disease, autoimmune disorders) start flaring more often, partly because depression disrupts self-care and immune function.
- Social isolation beyond preference
-
- You withdraw from people even when you want connection, but the effort feels unbearable.
-
- It’s distinct from introversion since it’s driven by illness, not personality.
- Sudden drop in libido unrelated to relationship issues
-
- Antidepressants can sometimes cause sexual side effects, but ironically, loss of sexual desire is also a common symptom of untreated depression.
- Increased use of alcohol, drugs, or compulsive behaviors to cope
-
- Substance use or behaviors like binge eating, gambling, or online overuse to escape the constant emotional discomfort.
- “End-of-day collapse”
-
- You can only function during the day by sheer force, but you mentally and physically crash as soon as you get home.

☐ I have trouble concentrating, remembering things, or making decisions.
☐ I feel tired all the time, even after rest.
☐ I move, speak, or think noticeably slower than usual.
☐ I’ve had thoughts of death, suicide, or self-harm.
☐ Therapy, exercise, or lifestyle changes haven’t improved my symptoms.

How to use and interpret this checklist?
- If you check five or more boxes, it’s a strong sign to book an appointment with your GP, psychiatrist, or mental health professional, especially if one includes suicidal thoughts.
- Even one or two severe symptoms (like suicidal thoughts, inability to function, or extreme hopelessness) should prompt you to seek help immediately.
- This is not a diagnosis. It’s a simple guide to help you decide when to get a professional opinion.
Key takeaways:
- Antidepressants are usually considered when depression is moderate to severe, persistent, and functionally disabling. That’s notably true if therapy and lifestyle changes haven’t worked.
- They’re most effective when combined with psychological therapy.
- Only a qualified healthcare provider can determine if medication is right for you by considering your symptoms, history, and other health factors.
- Antidepressants are not a quick fix and work best as part of a broader treatment plan (therapy, lifestyle, social support).
- They usually take 4–6 weeks to show full effects.
- A doctor will consider your personal history, other medical conditions, and potential side effects before prescribing.
