You said you have a new T appointment coming up, can I make a suggestion? Just glancing at your post and the disorders you have, maybe you should ask this new T if you are actually dealing with PTSD verses these other disorders.

The up and down and irritablitily and anxiety, these are also symptoms of PTSD.
And one day I asked my T about borderline personality disorder and he told me that often if you dig into their past these patients suffered abuse and they CAN be helped by therapy. He also said that it is important they are not being misdiagnosed.

Just a thought,
