Hi Justamom6,
I wanted to join lbjnltx in welcoming you. A lot has happened in a short amount of time, and there is much to learn. There is also much that can help. The best communication skill to start stabilizing your relationship with her is validation. It's a simple tool and also takes a lot of practice. People with BPD have a higher than average need for validation, and it's not necessarily something we learn to do in the normal course of parenting.
There are some
very helpful lessons on validation here on the site.
This will be helpful when your daughter talks about stress -- our instinct is to often invalidate (unknowingly) and try to fix problems for them. Sometimes the best way to do that is with
validating questions.
It's ok to tell your daughter that this is new for you, and that you need time to process what's happening. It's better to establish boundaries early, though I know very hard to do when you are so worried about your child's life and well-being.
We're here for you. You're not alone
