Hi Mominyyc, glad you landed here in the group

A lot happened on your journey here, some of it in your control (like you mentioned), and some of it not. The first thing I want to mention is that yes, many parents here have found hope, and while they sometimes have to grieve the future they wanted for their children, they have been able to make "the best possible" life for themselves. So much of it starts with what you're already doing -- reflecting on your past, your family, and your role. Once we "see the light" about what has made us who we are, we have the opportunity to make some changes, to learn some different tools and skills, that can make things "less worse". Not easy work, but possible.
A couple of things about your story stood out to me:
Today I’m taking her to a private DBT provider bc the waitlist for funded treatment is 18 mos long.
I’m not quite sure what I’m looking for here - I want to have hope - and I’m daunted with her cluster B diagnosis.
Let's start there --
it sounds like she is not actively opposed to DBT? Did she end up going? How has that been so far?
and has she received an official BPD diagnosis? was that at her psych admission? How has she approached the diagnosis (accepting of it, in denial, other...)?
...
What I also hear from many parents here is that coping with the incessant blame and verbal abuse is really, really difficult. So, in a sense, your D blaming you for everything is... normal, for a young adult with BPD.
How have you navigated the blame in the past?
...
Reach out any time -- let us know how you've been.
