Wanting to be a part of a group, wanting to fit in, and wanting to lessen anxiety is so understandable.
You do already fit in
I don't even like to be around people who smoke pot/weed. That includes family members who think no one notices that when they go off to the garage, they are energetic and bright eyed...and when they come back inside they are like a helium balloon that has been around for a week.. their faces are sagging and they are deflated and dull. The stuff they laugh at is sometimes funny, but not as hilarious as it would appear. It's very fake. Stay real!
