Thanks for the suggestions, everyone. I've thought about volunteer work before, so maybe I will give that a shot. I would really like to meet people my own age. In your experience, how old is the typical volunteer?

I just don't want to be alone. My greatest fear is that I will be alone my entire life. Honestly, it absolutely terrifies me. Sometimes I can't sleep at night because I am so worried I will never again have any good friends, I'll never get married, I'll never do all those things everyone else does. It gets to the point where I feel pain in the pit of my stomach. Anyone know if that is a symptom of social anxiety or Avoidant personality disorder?

Again, thanks everyone for the suggestions.
