I'm much the same, and came from a similar background; I didn't move nearly as widely as you did, but certainly did have frequent moves.

Seeing this described is inspiring me to try to develop normal social interactions -- or perhaps it isn't. Having actual friends, who agree with your goals and will support you in pursuing them, who you don't have to put on a false face before, is one thing; having long-term acquaintances who disagree with you and hold you back is something else. If you're comfortable alone, you won't tolerate unhealthy interactions as being better than none at all...
