You're making a series of assumptions here: that the problem can be accurately assessed this way, that the commenter is qualified to do so, that a message board comment is a suitable medium for such a message, and that the noise of this being an internet argument trope wouldn't drown out the signal of human concern. That's a lot of slack to cut "this guy has an anxiety disorder".
I do wonder what you'd say if someone described a physical health problem and people suggested they go see a physical health doctor.
