Well I have BPD, which for me comes with "volcano rage" issues. Like 99% of the time I am very chill and passive, but when I finally snap, I snap hard. It is an out-of-control rage that completely blows past my normal anxious, insecure side that would keep me silent and tolerating disrespect/abuse.

Because of this I have stood up to both of my parents (both abusers) in adulthood, not even by choice but because I just completely lost my ****.

I have to say that it's a part of BPD that I do not regret. Most of BPD sucks, don't get me wrong, but it did allow me to finally come exploding through the walls of disassociation and fear. Standing up to and fighting back against my abusers was an extremely cathartic and healing part of my journey.

So when I see people in your situation, I can't help but have a feeling of sort of.. cheering you on to stand up for yourself, to tell your mother how it really is. That she didn't care about your feelings or well-being as a child, and she obviously still doesn't care now, and you're sick of it, and not going to put up with it anymore. In the corner rooting for you.
