Hello Topsey,
I second the suggestion by
twojaybirds to take a look at the lessons to the right of this board to start.
I saw your question on the help desk about false memories, lies, and exaggerations. I assume that she's the outlier from her siblings. How early did her behaviors start?
I've known a woman, a family friend, since she was 9. Now she's 40. She has c-PTSD. It's said that this results from being trapped in a cycle of trauma from which there is no escape. I've had distance, but have followed this woman's life, and in my opinion, her ongoing trauma has been due to unhealthy choices and relationships. Blaming her mom is the easy thing. Turning inward to face the mirror is hard.
Whether your daughter actually has BPD or not, the behaviors sound concerning, and the tools here can help. You'll certainly find support by fellow travelers
