We have a very tumultuous on-again/off-again relationship. I look at his a Reddit account sometimes and he posted looking for advice on dating someone who has BPD. I assumed he was seeing someone else and got upset, only for him to tell me the post was about me. 

I started looking at what BPD actually entails. I know I shouldn’t self-diagnose... but the signs sound exactly like me. I don’t know what to do. I want to cry and wish I had someone to talk to about it but I’m scared to tell anyone. I feel like they’re going to think I’m crazy or trying to make excuses for my behavior.
