Everyone has low days, and hard times can leave you flat for a while. A bad phase usually eases as things change or as time passes. Depression is a health condition. It tends to persist, it affects how you think, feel, sleep and function, and it can improve with time and treatment.
If you are having thoughts of suicide or of harming yourself, you do not have to carry this alone. Call Tele-MANAS on 14416 (free, 24 hours) and speak to someone now. If you are in immediate danger, call 112 or go to the nearest emergency department.
How is depression different from a bad phase?
The main differences are how long it lasts, how much of your day it fills and how much it stops you doing. The World Health Organization describes a depressive episode as low mood or loss of interest lasting most of the day, nearly every day, for at least two weeks. The NHS puts it simply: depression is more than feeling unhappy or fed up for a few days.
In a bad phase, your mood often lifts when something good happens, and you can usually still get through your day.
A real reason does not rule depression out. It can follow a bereavement, a job loss or money problems, so “I have a reason to feel this way” does not settle the question. Depression is also not a weakness. The NHS calls it a real illness with real symptoms.
Grief is a natural response to loss, and it can bring many of the same feelings, which usually ease with time. For some people, bereavement can lead to depression. The NHS notes that feeling hopeless or guilt-ridden, or having suicidal thoughts, is rare with grief, so these are worth raising with a doctor.
What are the signs of depression?
Depression shows up in your mood, your body and your daily life, and it does not look the same in everyone.
- Mood: feeling sad, empty, irritable, hopeless or guilty, or having no interest or enjoyment in things
- Body: tiredness, disturbed sleep or waking very early, changes in appetite or weight, unexplained aches and pains, moving or speaking more slowly
- Thinking: trouble concentrating or making decisions, low self-esteem, thoughts about dying or suicide
- Daily life: avoiding friends and family, dropping hobbies, difficulties at home or at work
This list is here to help you put words to what you are feeling. It is not a test, and only an assessment can tell what is going on.
Physical complaints often come first. Indian guidelines note that people may go to general physicians, gastroenterologists or other specialists with these symptoms. Older adults may describe feeling nothing, not feeling sad. If this has come on during pregnancy or after delivery, see the guide to mental health in pregnancy and after birth.
How does a doctor work out if it is depression?
A doctor works it out mainly by talking with you and checking your physical health. The guide to your first visit explains what that is like. A psychiatrist will usually ask about:
- how long this has lasted and how it affects your day, to judge how severe it is
- any thoughts of suicide, because your safety comes first and the answer shapes the plan
- any past spells of unusually high energy, because bipolar disorder can look like depression and is treated differently
- your physical health, medicines and alcohol, because these can cause or worsen low mood
Simple blood tests, such as a blood count and a thyroid test, can help find anaemia or thyroid problems, which can also cause low mood and tiredness. With your permission, a family member may be asked what they have noticed.
Having a real reason to feel low does not rule out depression, so a doctor’s assessment helps more than guessing.
What does treatment involve?
Treatment is planned with you, and it depends on how severe the depression is and what suits you. Indian guidelines broadly set it out like this:
- Milder depression: talking therapy is often preferred, and medicine can be used if needed or if you prefer it. Exercise or a guided digital programme may also be considered.
- Moderate depression: the choice is usually between medicine and talking therapy, or both together.
- Severe depression: a combination is generally used, and therapy may start once symptoms begin to ease. When life is at risk, doctors may advise hospital care and consider electroconvulsive therapy (ECT).
Talking therapies for depression include cognitive behavioural therapy (CBT) and interpersonal therapy. Indian guidelines recognise that structured therapy is not available everywhere, so your doctor will consider cost, time and what you can reach.
Antidepressants are one option, and the decision is one you make with your doctor. The guide to antidepressants covers common worries, side effects and stopping. Please do not start, stop or change a medicine by yourself.
Improvement often comes gradually. Treatment usually continues for a while after you feel better, to lower the chance of depression returning, and your doctor can help you learn your early warning signs.
What can I do for myself alongside treatment?
Small, steady routines can help, even when you do not feel like doing them.
- Keep doing things you used to enjoy, even for a short time
- Go for a walk or do some other physical activity
- Keep regular times for sleep and meals
- Talk to someone you trust
- Avoid alcohol, drugs and medicines not prescribed for you
- Put off big life decisions until you feel better
These steps support treatment. They are not a test of willpower, and needing more help is not a failure.
How can family help?
Family can help by listening without judging, being patient and supporting treatment.
- Listen more than you advise. “Think positive” or “snap out of it” can leave a person feeling more alone.
- Encourage them to see a doctor, and offer to go along.
- Invite them for a walk or a meal, and accept it kindly if they say no.
- Help with appointment and medicine reminders if they want that, and leave any change in medicine to the treating doctor.
- Let them decide what to share, unless their safety is at risk.
- Learn the warning signs, such as worsening sleep, agitation or hopelessness, and tell the doctor early.
If you are worried about suicide, ask directly and calmly: “Are you thinking about suicide?” Research shows that asking does not increase suicidal thoughts or behaviour. Listen, stay with them, help keep them safe and call Tele-MANAS on 14416 together. Stay in touch afterwards too.
