At this point we can only really guess. It’ll probably be days or weeks before people can dig through the voting data and do substantive post-mortems on the 2024 campaign. Th economy seems to have played a big part. People are angry at high prices and they naturally punish the incumbent party even if the President doesn’t realistically control how much eggs and gas cost. Along with that it’s looking like there was a collapse in Democratic turnout in the Rust Belt while Republican turnout stayed steady, handing Trump narrow wins in Pennsylvania, Wisconsin, and Michigan. It also looks like the Harris campaign’s bet on Republicans who didn’t vote for Trump in the primary breaking for her failed to pay off.
Doing things and not spiraling is about all we can do at this point. I suppose it depends on the things you care about or want to prioritize The massive cuts to government spending Trump has talked about are inevitably going to impact services like Social Security and Medicare so mutual aid resources are going to be important for a lot of people:

At this point that’s mostly ballot curing, helping voters sort out issues with their absentee or mail in ballot. Some of these ongoing elections are incredibly tight and making sure those ballots are accepted could make a difference, especially in low profile races:
