I've been seen by a pdoc and he said he can't diagnose me. Not in the public system where doctors have no time. I could have anything from PTSD to OCD to bipolar to personality disorders, which we already knew. If I wanted a diagnosis, I could go to private institutes specializing in them. Such institutes will then probably make me fill the same questionnaires as available online for $200+ fees.

So I am asking the same question as Hazelgreen, at what point one could consider a diagnosis as sound. If a pdoc merely tics off checkboxes on forms based on a couple of questions asked, his conclusion will be equally as reliable as internet tests.

Why then not research symptoms oneself and choose psychotherapists with the right specialty, read self-help books, or ask the family doctor for a try and error selection of pills? It doesn't seem to get much better than that.
