It's a terrible situation to be in. About 3 months ago I lived out in the middle of nowhere, and I didn't really spend any social time with people. It wasn't until I left the place that I was social again. I just forced myself to leave that town, and go somewhere new. I think for me the new setting stimulated me, and made me want to be more social with people.

I know this not everyone can do this, but if possible leaving town every once in a while might help. It's nice to meet people that you have absolutely no connections too. Have you tried going to any meet ups or don't kill me for saying this a church? Where I use to live churches where a very important place to meet people. Your not going to like every group out there, but forcing yourself to go out, and talking about new things is one of the best things you can do with being lonely.

Of course I only know what works for me. I hope the best!
