Agreed! All these self-dxers do is make it harder for people who have an actual diagnosis to be taken seriously.  Like the ones I've encountered most often: the whales who wail (heh) about "muh anxieties"; no, you don't have an anxiety problem, you're just an insecure, whiny bitch. Then when someone who has a legitimate problem comes along, they get eyes rolled at them when they try to reach out.
