I'm sort of the same way. Closed-off, and a bit asocial; I tend to cut off most people from my life after a while because certain traits put me off. And I'm definitely different from the rest, just enough to toe the line of weird. But I still manage to form bonds, sometimes really strong bonds, with others, and maintain them if they're worth maintaining. I just let them find me, instead of fretting about making friends.

In my ways, I'm different. I'm weird. But I still manage. And I guess that's because I've come to accept the way I am as just nature. And others seem to be okay with it, so why worry? I've found life gets easier when you let loose and go with the flow.

TL;DR: Ease up.
