How can a change and get a life?

Hi, I'm 20 years old and male. Ok, I could write a lot but ill try and keep it short. Ok I have got no life whatsoever because I'm afraid to go out in public, get a job, because I feel like everyone thinks I'm ugly, and I just feel so irritated and paranoid when I am in public. In my childhood I was called names, about my eyes being 'big' and my nostrils being 'big'. I also got electrocuted when I was 4 years old. And I have just been rejected and taking advantage of all my life, I just don't know why. And now I'm at the point were I sit on my laptop allnight and sleep all day, I'm serious, this is all I do, I stay up all night because I'm alone and its peacefull and I feel safe. I just enjoy the internet, I love youtubem I gamble on poker and blackjack etc..and ye. I know this is very vert sad and I should be out doing what normal people are doing but I just can't, I am suicidal bcoz when I look in mirror I see an ugly person and I think I'm different and odd, and people laugh at me and talk about my image. Argh! I'm so depressed and angry, I want a life! Why is it that when I'm out I can actually see people staring at me as if I'm the ugly weird one? And please if u can just give advice on what I've saaid. Thanks.
