Need advice on getting my life back on track

At school I always had a decent amount of friends and I've had a few girlifriends as well, but since leaving school my life has hit rock bottom (I won't go into why) and now I have no friends, no girlfriend and no job, I could've done quite well according to my teachers but I got kicked out of school with no GCSEs. I honestly wouldn't know where to start, I'd like to get a decent job but I suppose I'd need a degree for that, and like I say I have no qualifications at all. I also could really do with making some friends (around my own age, which is 25) and getting a girlfriend as well, but I wouldn't know where to begin there either. I've always been a bit shy which only got worse when my life went down the toilet, I think I'm getting a bit better now but I'm still fairly shy. I honestly can't remember how you make friends or get a girlfriend and the thought of trying to do either is quite scary to me. I'd hate to be made a fool of. Also worth mentioning I want to move to a different town as this one is so small and boring, but that would make it even more difficult as I wouldn't know anybody. I can't help but thinking that this is my life forever, they say it's hard for any adult to make friends, let alone someone with Aspergers, and I don't see how I can go from unqualified bum to someone with a good job either.
