Hello 

The name is Mark and im really struggling and I have some questions that I hope you can answer. 

What is the difference between ptsd and bpd?

I find myself getting super frightened when a loud noise happens but idk if that what people with bpd also experience. I cant go to sleep at night and imagine the worst case scenario for everything mainly social interactions. As a matter a fact I had a dream last night of my friend who is a long time friend and he said something to me that triggered me and it hurt. 

I do find myself avoiding social interactions because I don't know how I will react but idk if that is part of bpd I would like to know?
