I have PTSD with bipolar. Mine is primarily from the violent loss of a family member when I was a teen. I also have some from a natural disaster that occurred here last year, but it isn't nearly as bad as that first one.

I've taken a class/group thing for PTSD that was DBT-based and somewhat helpful. I'm currently doing EMDR to try to neutralize it a bit. I can't tell whether it's helping yet.

I wonder if having BP makes us more vulnerable to PTSD. I'm sure I don't recover from stressful events as easily as others, and I experience emotions more intensely. I find that my proclivity for drastic mood swings makes PTSD treatment hard because dredging up those memories causes bad episodes for me.
