If your therapist does not defend you against remarks like this, you have a crummy therapist.
For those of us who have a DISABILTY that prevents us from being able to naturally and accurately read other people's nonverbal body language signals, analyzing things that are said around us is a survival mechanism. If we 'read more into things' that necessary, its in an attempt to make sure we don't miss something that would have been obvious to anyone else. Tell her to shut her cake hole and try living in your brain for a while.
And the staring is a normal thing for people with AS, too. Usually isn't about the person or thing we're staring at. As often a not, we're staring THROUGH whatever we're looking at, and thinking about something else entirely. If we were thinking about the person, most of us would look away to avoid eye contact.
