Therapists et al aren’t trying to cure autism. They help people navigate social situations, personal and social problems and confusion, and (this part is unrelated) emotional and psychological issues.
You may be able to benefit from a therapist helping discover a set of unspoken rules that certain social interactions are based on, and create a plan of action to engage using those rules, instead of “curing your autism” which isn’t possible.
Congrats friend. Are you happy?
