i.e. I cheated on my last girlfriend (horrible thing to do and I am in no way blaming it on mental illness) but since that’s happened, I’m now convinced my current girlfriend will do the same to me, because it was so easy for me to do it. Or cutting off friends on a whim because I’m splitting, what if my friends do that to me?

It’s like this paradox of extreme narcissism while being deeply insecure and it sucks.
