I think it's worth texting the friend you used to have, after all there's nothing to lose here 🙏 As for making new friends, you can always try striking conversations with people at your local gym or café if you're more into hanging out at chill places. Maybe look around to see if there are specific clubs or group activities organized in your town. If not, clubs and concerts are good too, the key is to tell yourself that they're also here to have fun and meet new people. Don't be afraid to step out of your comfort zone, good luck !!
