My suggestion is to join some kind of group in the place you live now. You can volunteer for a good cause, join a church, get in a book club, anything like that. You need to get out. Put your talents to use.
There's some truth in "out of sight, out of mind". I found that once I got past my mid-twenties, the people I knew in high school and college just sort of dropped off the radar screen. The close friends I have now are all, with only one exception, people I've met since I got married.
