How do i explain how i am feeling to someone? What should i do?

Well, depression is not a disorder to be toyed with. If you feel like crap, then why don't you get up and go out so you don't feel like crap? If you feel suicidal, tell someone, because if you finally do kill yourself (which you shouldn't) then they can help you through the depressing time. If you are depressed let everything out in a diary, or a journal. Vent everything out to a friend or parent. It will help, I promise
