where do sober ppl make friends

hey guys i’m 19 and just moved back to houston after spending a year in california for rehab then soberliving to get off opiates and now that i’m back all my friends are either dead or out of state for college.

the aa/na meetings i go to are cool but it’s typically late twenties and up so that’s why i’m here looking for suggestions.

I’m pretty shy as well tbh but nothing too debilitating.
