Err, I know nothing about this so I'm going to throw random things into the ring and hope they make sense, and help. XD

I think that the sessions you had may be enough to diagnose ADHD. I've never been diagnosed (parents didn't want the 'disgrace' of a screwed up kid I guess) but I know I have it. My teachers have known I've had it, everyone suspects it.

Depression I think you need more time then some punie little broken up sessions, can't you talk to a shrink and they diagnose it instead? Maybe you could try to pay a little extra out of pocket for longer doctor session for diagnoses?

I don't know! I'm sorry. I hope you can get it sorted out. I don't think the ADHD forum is frequented as much as some of the others. PM a mod and ask them to move this thread to the psychotherapy one or start another one there for better answers.

Sorry again, good luck!
