Loss of interest, decreased concentration and attention, feeling low and disturbed sleep or appetite are some of the signs of depression. Consult a psychiatrist who will assess you in detail. If you are feeling suicidal or hopeless, seek professional help immediately. Try some relaxation techniques like yoga, meditation and deep breathing. Indulge in hobbies. Spend time with people close to you.

Hello well sir it's better that a medical personnel recognises your condition as we need to see the symptoms and also duration from which you are suffering...I would suggest you to consult a psychiatrist first and take one counselling..Before taht you can talk to any of your peer, best friend or family...Thank you
