Find a local lefty group (anything from Food Not Bombs to SRA). Participate, listen, organize, help people where you can. I live in a remote rural area and I still have half a dozen small but active groups to choose from, you just have to get out there and find them.
Edit - it doesn't matter if none of the groups near you follow your exact variant of communism or anarchism or whatever, we have much bigger problems right now than leftist infighting. Always deescalate conflicts with people who are not the enemy.
Maia is a legend. She's the hacker who leaked the US No Fly List a while ago. Lots of other impressive things in her portfolio as well.
