Hi
PeaceMom 
I'm so sorry you had to find us but I'm glad you did - you've come to the right place for support as you navigate this intense relationship with your daughter.
It sounds like you've really been through a lot with your daughter, my heart goes out to you. You will find many others here who have experienced, are experiencing, similar situations - you are not alone.
Do you have any support in the real world? Many of us find working with a therapist (T) who has experience with BPD very helpful.
I'm short on time and must run, but I wanted to welcome you and tell you things can improve - we've lots of tools and articles that are helping many of us work toward more peace in our lives.
I'm sure others will be along shortly, hang in there!
