Slow introduction to stimmuli. Meaning you have to do it in steps. Maybe be satisfied just being around specific people. Then when you are alone with them try to talk one on one. Then after that you can try taking two at a time. Then surely after a long while you can do it in groups.

Join the upcoming speed shuffle event which would place you alone with people one on one 5 mins at a time and see if you can break out there.
