chin up fella. I've felt like you have in the past and one of the key things that cheered me up alot was having friends around and when they werent there, (2am etc!) Crap TV like Jerry Springer just for laughs. Even if their aren't many friends on the scene, there's always be one who's gonna try cheer you up!
Dont worry about being single, some people can learn to love the single life, you just need to be doing the right things! such as activities that interest you. If you want a relationship to happen, it wont! so just relax, have a good laugh - your confidence will shine through and win you over a lady and something will happen. I met Ems through my website! Didnt expect that to happen at all!!
If home life isnt that bad, then don't move out yet. The last thing you want is moving into an empty flat when your feeling like that. Go watch football with your dad or something when the season starts and build up a relationship if you havent got one, as that'l make you happier too.
Also, don't worry about losing mates as if you start a new activity, you can make new ones. The good mates will keep in touch.
Finally, please dont use 'txt speak' 
Hope that helps
