New faces make me nervous

I have a terrible case of social anxiety and Ive been trying to work on it by going with a group that im not fully comfortable with. Like recently, i went with a group of 6, myself included, to a restaurant. In my eyes i did good, ordered no problem, and talked with everyone at the table no problem. No one cared. Im not going around seeking approval but if someone is going to complain about it i feel as though that should at least get some acknowledgement. Like i tried, even after i was given the option to not go, i still chose to. The reason its not progress apparently is because i told them it was easier for me to go in places in a group. Okay. Fine, on a completely different occasion, i go into a new mechanic shop just me and my gf. Now there weren't really ppl there other than the mechanics but, because i go into my mechanic shop, the same mechanic ive gone to for 4-5 year now, its not progress, even though ive never been there or met these ppl before.
