We're all normal people. It just some of us are either wired differently, had bad experiences and maladaptive responses, or both. I think some therapy approaches try to find the reason behind the things that trouble us and/or others and help us find solutions. Or something like that, I've never gone through that myself. Do you think you'd want to find a way to "get better" or find ways to better cope with the things you deal with? Maybe both? Maybe just finding the reason is comforting on its own, like how you've discovered some of your reasons.
