The thing with PD and PTSD. Is if you acknowledge them, work on them they can go away leaving you with only the bipolar to deal with and it would be easier to deal with as a single issue. Deny PD it’s just going to keep tripping you up. I had ptsd diagnosed first then later bipolar. At first all they did was throw the kitchen sink at me in terms of drugs. Which just made therapy impossible. I stopped taking pills and therapy became easier I work specifically on the ptsd. And got a handle on it. That made the bipolar much easier. To treat and I’ve been stable for more than 5 years now. It was hard and at times I wanted to give up but my therapist would point out the progress. The first thing I got a handle on was the hyper vigilance. That did help a lot. For a PD you would need a therapist trained in DBT, for the ptsd a trauma based therapist for the bipolar a pdoc. Preferably one that doesn’t over medicate or try to medicate other symptoms but sticks with the bipolar.
