Alone in the world

I have finished secondary school and I was never mr popular. For years I only had one real friend to hang out with and it's hard. I meet and few more people and then school wasn't to bad but when I left i realised something. These people were into of games and would rather spend a night in playing halo when i want to do things and so what could I do? I don't have many friends to 'fall back on' and the ones I do have are not like me and don't want to just go out and do stuff. I only have one friend that will do that but i don't want to always be a burden to her. So yer I know what is like to be alone and it gets you down a lot but I don't know how to get out yet . . .
