Hi lostinsidemyself, I have both BPD and PTSD, although BPD is definitely my main issue. I have other issues as well. Actually, I only found about the PTSD a few weeks ago – although it was clearly written in my file I had never noticed it, so for many months I didn't even know I was diagnosed with it.

I'm afraid I can't help with the flaring up of BPD, because I'm stuck myself. I haven't had good therapy/therapists so far so I was never really able to identify what my triggers are and, especially, how to work around them.

However, I just wanted to say you're not alone.
