Saying most mental health professionals are a joke is perhaps a little harsh in my opinion, after all they are trying to understand and treat the most mysterious and complex things known to man.

We don't diagnose diabetes with a list of symptoms because we have a lab test (where we have picked an arbitrary value, but that's another story). We have no lab test for add. That is frustrating, and I think that adhd is probably overdisgnosed, but I think most are doing the best they can.
