I can overwhelm folks with my emotions. When I have the presence of mind I ask my ASD-like daughter what reaction she would be comfortable with (big, little, medium) --- to my surprise sometimes she says "big!" in an exciting moment and lets me dote on her. If you have the ability, ask him --- if he says medium or little, then make sure you take another time to do big for you! You can do big here!!
Wishing you both healing and wellness.
