I agree - in the past sometimes I haven't described my symptoms well enough, so I wasn't being clear about how bad things were, and also didn't know what symptoms to mention because I didn't know they weren't normal.

ADHD was a much easier diagnosis than bipolar (I had 5 evaluations in under a year before I'd believe it) but I've still been re-evaluated for ADHD at least 4 times over the last 10 years when I've gone to new doctors and therapists. The fact that they come up with the same explanation every time, and that the meds help, is pretty convincing.
