I sort of know what you're going through. I don't really talk to my old friends anymore, we lost touch, but I do accasionally see them at college and talk sometimes on the internet.
Also I'm not particularlly good at making new friends and, generally, socialising with people due to the fact I have no social skills whatsoever, because I've had to move alot (dad in the army), and I thought what's the point in having permanent friends if I'm just going to move again? So I only made a few friends in each place I moved to. Also I never got into a relationship with a girl, because I wouldn't be able to live with myself after breaking her heart.
Edit: Sorry for jacking your post. :/
