Really cannot emphasize enough the emotional benefit of picking a spot where you can have an outsize impact and digging in to really work on it in addition to your other efforts. My contributions to protecting anonymity online have been SUCH a motivator for avoiding despair.
In 2020, I worked a voter assistance hotline and helped dozens of people figure out registration and voting in a complicated state. It was immensely satisfying and I am signing up to do it again this cycle. It was relatively low stress, in the calls were from people who WANTED to talk to me.
Maybe your spot is keeping your local school board out of the hands of bigots or organizing people to advocate for climate policy or providing tech services to a local candidate's campaign. Maybe it's writing postcards to voters or phone banking or doing jail support. Pick something. Anything.
