I think if you possibly can, you should just jump into it. Attending meetups is a great idea, and group activity clubs work too. Meeting new people is actually a bit intimidating and effortful for most people, not just for people who stutter. Once you relax and get into a fun conversation it's nice, but everyone faces the possibility that that won't happen and that they'll feel bored and marginalised all evening. Minimise the chances of that happening by putting forth some effort and getting in the zone: smile a lot, ask people questions about their interests and life goals, try to feel and display an enthusiastic interest in the answers. Some people make friends through humour, which looks very effective although personally I've never been able to do it. Basically you're in the phase where you need to invest some effort for little immediate reward. The reward comes later, when hopefully you've made some solid friendships and feel happy and comfortable around those people. What do you think? Can it be done? Good luck!
