I agree with Rive. Diagnosing someone carelessly is dangerous.

All my diagnoses are either from informed past evaluations or evaluations at my own request. Nine years ago I asked my Pdoc and now ex-T to diagnose me at the same time. I wanted to see if they came up with different conclusions. I also wanted to see if I had BPD (you shouldn't diagnose that in childhood). A couple of weeks ago, I asked L if I had PTSD. We are starting to do the evaluation, but not for the diagnosis sake, just for personal reasons.
