I have found that making friends around a hobby or activity is quite easy even as an adult .. Throwing yourself into a hobby (photography, pickle ball, boardgames, running, etc.) and you will meet people who love that hobby and throw them selves into it completely .. They will talk to you for hours about it .. If you are a nice person and just ask for help, people will be available to help you in your journey .. In those groups, you will likely find a few people to start developing a friendship with .. I think it takes the risky and scary part of making friends away as it just feels like hanging out until you find those persons you click with
