Honestly paranoia is the worst part of BPD for me. It's so intense all the time. People who I consider my closest family and friends offer me support, and when I open up I berate myself and doubt their intentions. Like my paranoid self is convinced they're doing it out of obligation or noseyness instead of genuine care and wow, am I really too stupid to see that? So then I close back up and don't speak to anyone only for it to happen all over again. It's hell. And it makes relationships and friendships VERY hard.
