If you have been suffering this condition for long now is the time to gather the courage n see a good doctor who can help you with ur depression. Medicines plus therapy will conjointly help you. Life owes you nothing. It’s a harsh truth, but accepting it will give you the motivation to create the life you really want, without expecting it to be handed to you. Next time you find yourself thinking, “Life is so unfair,” stop. Ditch the victim mentality, and focus instead on actions you can take to change your situation. If you’re unhappy with your weight, take the first step and sign up to a gym. If you hate your job, start sending out applications. It’s down to you to create the life you want.While support from others is great, the only person you can truly count on is yourself. When working to create the life you want, you might find that friends and family cast doubts on your plans. Remember that nobody knows you better than you know yourself, and work on becoming your own biggest supporter. Changing your mindset truly can change your life. Stop blaming your problems on external factors, and start taking control of your actions.

Since your depression is for some time, u will require medications for sometime and some sort of psychotherapy. Remember all types of psychotherapy are not suited for everyone. Which one u will need can only be decided after listening to Ur history. U will also need to do some blood test. Overall I don't think it's a major thing to worry about. U will get well after proper treatment.
