You have a lot on your plate. Have you ever read about these things called DBT or CBT? You might should just do a quickie lookup on them. I have found both to be very, very helpful in managing my psychosis and depression, not so much so for mania--that is for me, mostly just a med thing. I also have severe, longstanding PTSD and again, both CBT and DBT can be super helpful, at least for me they are.

The precise interrelationships between all these different illnesses are poorly understood. I would focus less on trying to tease all that out, because that could drive you crazy. I would focus more on getting some really good skills. Check these two out. You might find them useful.

Good luck to you!!
