What's the bet, that there will be other people, around your age, that may well feel the need to join or start a band in your area as well.
Local Music groups on Facebook, Gumtree (yes, people still use it!), Ad's in music shops, talking to folk on the local Jam / Open Mic Night scene. There may well be a few false starts along the way, but if it gets you out playing again, great.
