Hi Mom4278
I have a D 16yo who also was dx BPD. We have also struggled with her behavior since she was in elementary school. She was dx then with ADHD, anxiety and ODD. Some things that are helping us - we found a DBT practice that works with families. My D has her own T, my husband and I see another T in the practice for skills training and support. I know that DBT practices are difficult to find.
We also signed up for Family Connections and just completed the intensive weekend program. Here is the link to sign up...
https://www.borderlinepersonalitydisorder.org/family-connections/The program typically is a 12 week in-person or telephone/webinar program. There is a long waiting list, but so very worth every minute.
We are learning skills to change how we respond to her and it is slowly making a difference in our family. It doesn't always feel so tense and stressed in our home 24/7.
Self care is also critical...a couple of months ago I started to practice meditation for 5 minutes every morning (well, most mornings ) My husband and I try to take a walk together every night and we also go out to dinner, just the two of us, after meeting with our Therapist every other week.
This forum has also been a great place of support, information and resources.
Everyone here understands, is non-judgemental and gets it..
Sending you a hug
