Hi PurlTopia,
Glad you found this site.
I don't know that there are many of us with BPD Mom's who haven't wondered the same, do I have BPD? Rest assured, if you did have it, you wouldn't be here and you wouldn't have the clarity of mind to ask that question.
I have a BPD mom and a suspected BPD step daughter. Some of the ways I cope are 1) going no or low contact 2) finding a support system, people who get me and who get this situation. It is pointless talking to anyone without mentall illness in their family, or in denial about mental illness in their family, they will just glom on. 3) focusing on myself and finding out who I am and letting myself be a mother to myself. I have also sought various types of therapy, including cognative behavioral for childhood trauma, and I also tried hypnotherapy. Both were very helpful to me. In the past I have taken anti anxiety/anti depressants, but was able to ween myself off those many years ago (they stop working, did you know?)
Please post more, and know that we care here and we understand you.
