Why do i hate myself so much?

I am a guy I'm going to turn 17 in a few days and I have not done anything good in my life. I have never had a girl friend and don't really talk to any either. I don't have a job never had one and I have zero self esteem I am always in my room sleeping or on the computer doing nothing. I have very bad grades in school because I am always sad. I am scared to talk to people and my parents always give me crap about being lazy and not doing anything right. I have had thoughts of suicide, but never attempted and probably wont. I don't find any thing interesting I just don't know what to do anymore.
