do not see any doc. Take responsibility for your life. Try and relax. There is nothing wrong with you; we all feel depressed from time to time. Try to develop control over your senses (like the famous drawing of Lord Krishna holding five reins of a horse, representing our five senses). What will help you in this case is: a) define what you want in your professional life. If what you define professionally is driven by your passion/ knowledge, its probably better. b) define what you want in your personal life. If you aim for a peaceful/ loving/ sharing life, it probably would serve you well. There might be instances when its very difficult to be loving/ peacheful etc., but try to minimize these instances and still when confronted with such instances, try to remain silent or get out of the situation and go for a jog or take deep breaths. c) work like an ox towards goals a) and b).
Lastly, try to follow a diet pattern (heavy breaker, moderate lunch and light dinner; throw in a little mini-meal in the late afternoon comprising fruit/ nuts). Your diet should comprise fresh fruits/ veggies, whole wheat, dairy, lentils/ beans (chicken and fish if non-veg; avoid red meat). Try and follow a sleep schedule (preferably early to bed and rise). Try to get 15 - 20 mins direct sunlight exposure before 8:30 a.m. Also, try and do some aerobic exercise
every morning (maybe dancing/ running; whatever suits you.)
Take care. All the best.
