Trauma being described as a disruption in healthy brain development, for this particular conversation. The reason my emotions are like they are, so explosive and out of control and intense, is because I wasn't allowed to express them growing up so I never learned to process them appropriately. They stay inside building up and slip out in toxic ways or rush out explosively- not just anger, but all of them.

How do people get the same intense, uncontrollable, wildly fluctuating emotions without some kind of trauma that causes someone not to develop their emotional process correctly? Is it even BPD if it's all based in trauma?

It's not that I don't believe it's possible, I guess I just can't understand with the info I have now and I'd like to. I want to better understand people and maybe even other parts of myself. Are there any solid causes that psychology or psychiatry is certain of? Can anyone with BPD but not trauma tell me what they think about it?

Sorry if this is rude or something, I'm really just trying to empathize and learn. Thanks for your time.
