>don't know if i'll keep it up

That's the only part of what you wrote that deserves criticism. Try it. It's going to take a while. I'd maybe focus less on "I gotta find a band right away" and more on "Let me find someone who can play guitar and see if we can come up with stuff" first. Like, the whole discord thing is probably overkill.

That or, fuck it, get a cheap guitar or keyboard and just mess around. There's a ton of resources to learn how to play where you don't really have to pay anyone for proper lessons. I'm honestly jealous of the options someone has if they want to learn to play now.

Edit to add: obviously, if you try and then give it up cause you're not into it or whatever, that's cool. No shame in that. It's not for everyone and there's a pretty high bar before you feel like you start getting back what you put into it. I just meant "don't just quit now. go for it"
