I have given a great deal of thought to things like this. I can relate a lot to you. I do a lot of reading on the subject and this is one of the good articles I have read.

A lot of interesting commentary on diagnosis in that one.

*EDIT* I think this is the article I meant to link. Both are good but this one directly addresses your topic better.
