Hi SadKate,
We are sorry to hear of the difficulties you are facing with your daughter, you will find that it's a familiar story here. You've found the right place for knowledge, understanding and sharing. Good on you for taking extra steps to try to better your situation. One thing many of us have learned is that we cannot change our person with BPD (pwBPD), but we can change how we react and communicated with them. Handling that in a more healthy manner can have a positive impact on your situation. To the right of this page you will see some tools and lessons that can help guide you in improving the way you react and communicate with her.
If you feel comfortable, give us a little more background on your situation. How old is your daughter? Has she been diagnosed? What are some of the more frustrating things you commonly have to deal with?
Keep sharing! We are here.
