Welcome to Psych Central, Enceladus!
I do have BPD, yes. I also struggle with PTSD and treatment-resistant major depression. It doesn't sound really good, but I *think* that's because of the typical images pushed in general society.
There are techniques that we can study and practice regularly, to help us live pretty normal lives with BPD. It takes motivation and commitment. But, it CAN be done. The BPD certainly adds a big challenge to our lives, but we can work through it.
