Move to another country.

I'm serious, that's what did it for me. I had a very lonely and isolated life before, despite of my efforts to be active and social. Since I moved to a different country, I have a life that's more in line with what I expected it to be like. It's not all sunshine and rainbows. In fact it's still pretty hard, but I'm actually progressing now instead of feeling stuck. I have a few very good friends and a bunch more casual friends. It feels good to finally have people recognize my efforts and appreciate my personality, instead of feeling like a ghost who doesn't really exist.

And yeah, I know this won't solve it for most people, I just figured I'd share that it did for me.
