I know I'm depressed,I have been for probably three years now and I haven't told anyone because I'm embarrassed. Since it has been along time it's starting to get worse and I've harmed myself many times and have almost committed suicide multiple times. I want to tell someone but I don't know how and I'm afraid if I don't get help soon I might do bad things. What do you do when you tell your doctor you are depressed? How do they diagnose that you might have depression or anxiety? What do they do?
