history: I moved away from my home town last year and I regret it. I moved away from my home town last year for a new job. I sort of regret it since I don't have many people to talk to. I know how you feel.  I moved about 3 hours away from my hometown for school and stayed for 3 years and hated it.  I moved back to my hometown and am so happy now.  I'm sorry you're having a tough time.  Have you gotten out and tried to meet people?
current: I have. I'm pretty introverted so it's hard for me to meet new people. I'm considering a move back.
next: I would go with your gut.  Sometimes things don't work out, but you might just need more time to meet people and might want to hang in there.  I hope you meet a best friend soon!
