Hi Maka58
The situation with your middle daughter sounds quite difficult indeed. BPD is a challenging disorder and your daughter sadly exhibits some troubling behaviors.
I am very sorry your granddaughter got hurt back then as a result of her mother's behavior. How is your granddaughter doing now? How is her relationship with her mother?
It's unfortunate that your daughter seems to refuse treatment. You mention she's completely against meds, do you know why? Has she perhaps expressed why she's against meds?
Considering what you're dealing with, I understand how anxiety might be an issue for you. You also have your own health issues to cope with which also isn't easy. I am glad you reached out for support and advice here as we have many parents with BPD children who will be able to relate to your story.
Take care and welcome to our online community
