Have you ever thought of moving to staying at uni?
That would be great for you, you would also do a lot of "growing up" if you see what I mean (i'm not insulting you)
Ok have this as an example.
I'm 18, and for this years new years I went out with 3 guys to the local O'neils (which was packed but we got early and claimed a table) and that night I met one guy who I would now consider a decent friend and me and him along with a few others (friends of his which are now my friends as well) go out, and we see others we met on New Years and always have a great time socialising etc.
Seriously dude, I know Uni studying etc is important, but get a few friends togethor and go out.
Will do you some good
