depression

I have been depressed for a while now. Im 17 years old, hate school, had to stop my hobby which was one of the few things I loved in life due to injury, recently had an operation, I can't get a job anywhere, don't get on with my family, don't have friends I can truly talk to, and I am becoming increasingly withdrawn. I have had suicidal thoughts, though not ever considered following them through. I don't know what to do anymore. I can't seem to be able to talk to anyone and im always bored, so I just sit and think about all these things. I feel very lost.
