I've been getting really bored with stuff lately?

I used to have a pretty decent life, though I always felt like the third wheel in stuff like social activities. I used to have a best friend, then he turned into a a cussing, idiotic jerk. Sometimes I wish we still hung out but now I realise I'm better than that. Now I'm kind of a loner and I hate it. I think about it and I've never had a friend I could act normal around. I never leave my house anymore. I want to go out and see a movie with friends or something but I have literally none. I was sort of accepted into 1 friend group but I quickly left them because I still couldn't act normal around them and some of them were jerks. But I've been so bored lately. Haven't done anything in months. I feel I've been stuck in a rut. I'm up on facebook all night, or xbox till 1 in the morning. I hate it. So I thought I'd turn to people on the Internet. They're always literal, kind and considerate. Help?
