Hey, deep breaths. I'm a loner myself, but you don't need to be active on platforms like teams. You can just text chat on discord for example. It's a great place to find people to work with too in the team finding thread. Here's an invite link if you're not already there: https://discord.gg/3PAcvqzfg
Most importantly, don't take game jams too seriously. There's no prizes in this one, you don't need to use GB Studio because we only care that it "feels" like a gameboy game, and there's lots of people looking for various roles. If you don't finish your game - don't worry about it. Just be proud you tried to do something.
Hope you decide to give it a go. It's a really rewarding experience, and jams really help me get out of a creative rut.
Remember though, it's just a jam. We're all here for fun, so take it easy and don't worry too much.
