I wonder if this is a symptom of bpd, or if anyone else goes through this. Basically whenever something happens to me I have no idea what is the appropriate way to react. For example, if a friend said something that hurt my feelings, I don't know if I actually have a right to be hurt, or if I am just being dramatic. I just spend a lot of time thinking about wether I should say something, that I'm hurt or that I want them to apologize... etc. or if I should just play it cool and pretend it didn't bother me. Then I wonder about the consequences of my decision, for example, if I had said something maybe I'll be perceived as dramatic and that it wasn't really upsetting, but if I didn't say anything then people will just keep hurting me and getting away with it because I never say anything. 
It's very difficult sometimes especially in relationships to know if I should say something or not.

If anyone goes through this, or has any advice please don’t hesitate!
