Mental Health Support

It never bothered me when someone self-diagnosed but maybe I'm the exception to the rule. I would at least discuss it with them and give my official diagnosis if I felt it was therapeutically appropriate.

Use the non-technical words. Avoidant is a nice fancy word for very very shy, in that you avoid possible human interactions. I'm no expert on Avoidant, but yea, use the non-technical words. No therapist will object to that, guaranteed. Also, no psychiatrist, clinical social worker or psychologist will object either, guaranteed. Shrinks (psychiatrists) like to get into territorial pissing matches over words, so yea, just avoid that nonsense.

My $0.02, hope it helped.
