Look around your town and try a few regular local group activities. See "third place" for ideas. Be patient with yourself. This will take time, and that's okay.
Some of my most durable adult friendships started at group ballroom dance classes. The studio was a 15-minute drive from my suburban home, twice per week, and focused on social dancing, not competitive. I don't think dancing was the thing that made it work, but funny teachers and regular faces. That studio closed (pre-pandemic, thank goodness). No studio since has recreated the magic, but other activities have.
