Hi
Drainedandexhausted and

While I'm sorry for the circumstances that brought you here, I'm glad you found us and have reached out for support. I can only imagine the heartache of being the target of your daughter's anger despite being the loving parent you have been, offering respite from an abusive, neglectful childhood, loving and caring for her as your own child.
We have lots of stuff to read here, different tools that help us navigate these emotionally intense relationships. A good place to start here is by taking a look at the post pinned to the top of this board,
HOW TO GET THE MOST OUT OF THIS SITE It's got some of our best articles laid out in an easy format.
Reading and learning all you can about BPD is the first thing I recommend, along with continuing to post here - having a support group is critical and can help you feel less alone. We all need a safe place to talk openly about our feelings and BPD Family is such a place. You are not alone, we get it as nobody else can.
What are the behaviors you find most challenging in your daughter,
Drainedandexhausted?
I've gotten some great, practical advise here in dealing with my BPD daughter, and things are slowly improving. It helps to get a broad picture of the behavior so we know how to best support you. Are you finding time for things you enjoy? Taking care of ourselves is priority one
Again, welcome!
