You should meet with your friend and discuss your concerns. Tell her you are worried about her and do mention Asperger Syndrome, but not the incident with the counsellor. Suggest but do not diagnose her with the syndrome. Only a qualified health professional can do that. She may not even have Asperger's, but another condition that resembles it, such as dyspraxia.

Heed Jimrat's advice. He has made a lot of excellent suggestions.
