I'm actually doing this. I don't feel suicidal (never would) but I do feel that people around me were so different that if I stay here, my Self will implode socially.

A suggestion for people who are at the point where moving seems like a decent alternative: In OKCupid, the match-making website, there is a long set of questions you can respond about yourself. If you fill those up (say 90 out of hundreds) you can ask the algorithm to find people who are high matches to you as Friend, and high matches to your romantically (correlated but distinct measurements).

If you ask the match making algorithm for those who are similar everywhere, you'll see where you may fit in better. The vast majority of people that show 90% or more correlation with me are concentrated in 2 areas of the world, New York city and California (SF Bay in particular), this is one of the indicators I choose for where I'll try to live.
