Repressd--oh boy do I feel ya!
My mother was undiagnosed NPD BPD, and I knew by the time I was 17 that I was supposed to be myself, "her way."

It's an entirely crazymaking situation, for sure. I too have been a 'late bloomer' since I married somebody with some of the BPD traits and continued my "trying to keep the peace" ways, which absolutely and totally do NOT keep the peace!
i'm familiar with the feeling of not being able to do anything right, and just when i'd think i'd finally figured out how to do something that would make her happy she'd change the rules! You have found a place of kinship for sure, there are many many similar stories to yours here at bpdfamily. I know it helped me a LOT to find that I was not alone in my feelings. In fact, I've been in therapy for 12 years now and I feel like I'm finally good with who I am.
I've had to learn too that beating myself up for things I didn't do "back then" because I didn't have that knowledge yet is pointless. All I can do is move forward, learn how to take care of myself in the here and now, strengthen my boundaries, and grow into the best me I can be.
If you are here and you're looking to make changes you will be on the road to making some peace with the past that you can't change, and moving into being the best YOU. And that's a really good thing!

I hope you get even half as much as i've gotten out of my time here--there's so much great information and so many members who know exactly what you're talking about.
this is the first book I read on the subject:
Stop Walking on Eggshellsand she's written a newer one that I've started, and it seems to be set up in a pretty organized way:
Essential Family GuideHave you read any books on the subject yet? What have you read on bpdfamily here? This is a good little video that will probably ring true:
Video-What is Borderline Personality Disorder?i'm looking forward to hearing more about you! and by the way, you are still plenty young and have lots of time to have a very fulfilling life. It took me a while to silence the voices of my parents in my head, but it can happen.
