Okay, experienced Florida activist and volunteer here - Gillum's org is called Forward Florida Action if you're looking to join. If you're young, say, high school or college age, March for Our Lives Florida is a great place to start. You can also join individual campaigns, like those for state house or senate, federal house or senate, or any of the major presidential candidates later into primary season. There's also the state party, though it is somewhat corrupt and takes questionable donations at higher levels. If you have any questions or want me to point you in a direction based on your location, feel free to PM me here.
As for the poll results, I understand it's hard to make time to do more than vote, but good candidates desperately need help for simple tasks like organizing, mailing, door-knocking, and so on. Give a few weekends of your time to someone you support. Please. Good politics doesn't happen without good people.
Addressing the social anxiety thing, campaigns will pretty much always offer to pair you up with someone who has done the job before so you don't have to go out there alone. It's inefficient at first but to them it's just training another good volunteer.
