None. There's one person who I've known literally since he was born (our moms were best friends) and I haven't spoken to him in 2 years. Other than that, people from school and other friends have eventually faded either because we grew apart or because I stopped talking to them. There was another friend I had who was really great, he was a bit like me and very loyal, just a good guy and a good friend. After I started becoming more reclusive I basically cut off contact with everyone, and I remember out of the blue he called me and was asking how I was and everything. I kinda just acted like everything was cool and basically lied and said I'd talk to him soon. That was like 5 years ago, and eventually I moved so he couldn't even reach me if he wanted to :

: and I've always regretted doing that because he was a good friend. I just couldn't face anyone who knew me because I was so embarassed by my lifestyle and what I had become, and eventually too much time passed. Maybe one day I can apologize to him (and others) and let them know that it wasn't personal, though I think they know me well enough to know that it wasn't.
