It's interesting isn't it, what psychiatrist say. My original diagnosis was not right, but even at that time my psych agreed with me that meds were not helpful(after I titrated off ad's without telling him and nothing changed!), and that therapy was definitely what I needed.

It wasn't until meeting my current therapist and seeing him for a few months that I questioned my diagnosis, he told me what he thought it ought to be(CPTSD, MDD in remission) and then met with my psych and had him change my 'official' diagnosis.

I know that talking is helping, slowly, but it really is helping. It has taken me more than 18-20 months to get to a place of trust with my therapist, but even that process has been helpful.

If it were me, and a diagnosis were important to me(as you are asking)....then I would just ask, point blank, no maybe's, please give me a definitive diagnosis please.
