seriously. it's not that big a deal. if people in gaza are still standing up to their oppressors every day then you likely have zero excuse for not doing more IRL shit (political reading and writing at home are good, but don't mean anything if you're not applying that theory as practice and then assessing the results and adjusting your practice accordingly).
If I can suggest a resource for one of these problems - COVID - for people like me who can't take on the risk of (re)infection/are already too disabled by COVID to do anything in person. Basically try joining a mask bloc or similar from the directory here, the people there should understand better than most your need for protection from plague https://linktr.ee/COVIDAdvocacy
