Recently I started to think about the reasons that made me develop bpd. I'm sure emotional invalidation is the one of the main reason.
I won't tell my life story here because it would be long but my mother who also have bpd (got diagnosed last year) was very instable and sometimes violent. My father was always working because he was always stressed about money. And when he was there he was stressed about my mother and her moodswings. So me and my brothers didn't have place to really have emotions or feelings because the only "important" emotions in the house were my mother's. She would control everything/get really really mad at little things. She was always screaming and blaming people of things they never did and in the worse she would get violent and throw things or hit us. Everybody was always stressed about how she would react to things. 

And I think its probably one of the reason with genetics that I have bpd now. And when I did my research I found this article (I'll post the link in the comments) about how emotional invalidation may cause bpd. Idk if it's legit or not but it made me think about my childhood. I wanted to share my story and see if some people here could relate. Sorry for my bad english btw.
