Morning YogiBear - hope you're day is going well so far.
I've gained a great deal of insight from reading Marsha Linehan's DBT workbook that addresses how to develop specific skills for the issues BPDs deal with it. While my therapist insists I'm not BPD I see that I have many of the traits, such as impulsive anger. This is the workbook:

One of the things that Linehan espouses for treating BPD is "mindfulness." There's a great book about this and how it can help you deal with stress and trauma (which we can apply to the stress and trauma caused by our BPD parent) by Jon Kabat-Zinn called "Full Catastrophe Living."
