I have BPD (diagnosed around 6 years ago). Once I got my diagnosis every decision I'd ever made in my life, every emotional meltdown all made sense. 
When I looked up the symptoms of BPD later that night, it was like reading a description of my personality. 

However, the thing that has always stood out to me about BPD is that it's supposedly caused by trauma. Every article I read says it's caused by trauma- but I DON'T have trauma! 

I really, really don't. Even my parents can't think of anything traumatic in my life.
The thing is with my BPD, is that it feels like I was born with it, not developed through some kind of experience. 

I just came here to ask if anybody else felt that way? 
I know only two other people with BPD and they both talk of traumatic events that they think led to their BPD- I don't have any. I can't think of any event. 
Maybe I'm the first in a million to be born with BPD 😐
