It's not that abnormal - at least, I get it, as I have considered stopping allowing people to get close to me because I'm so sick of them hurting me. You feel like you'd be better off alone, but ultimately I don't think you would. It feels like stupid little things that I get upset about too, but I just think, I would NEVER do that to you so why are you doing it to me? I forget that everyone isn't the same and people's brains don't work the same way.
