I still don't understand why so many people are against self-diagnosis. Someone is suffering and trying to find help, a lot of people, especially minorities and women, can't find it professionally. What's wrong with those people looking for help themselves? Having a word for what is different with you helps finding this help.
I'm not talking about people claiming to be autistic and demanding attention and accomodations, that's a whole different story but trying to keep people from finding help themselves seems to be very wrong to me.
