You do you. Continue to vote, and if you can find a local cause that you can give time and attention to, do that. If you can find some small way you can help people who are affected, do that. Subscribe to news sources you trust and think are shining a light on the right things. Maybe setup small donations to candidates you think are pushing the country in the right direction. Not everyone needs to fight every fight.
I do donate to candidates that I think are less evil than the average politician.
A bit more locally; my wife is Mexican and as such I have a lot of Mexican in-laws. I have been helping my brother-in-law deal with immigration lawyers (and paid for them) in hopes that he might be able to get his citizenship soon-ish.
If I felt like anything I did in the grand political scope would do anything, I'd do it. I used to be a lot more active in this stuff, but it's pretty easy to get disillusioned and cynical with this stuff.
Impossible to care about everything all at once, and easy to get disillusioned and shut down to nothing. Keep pushing in the ways that you can, give the energy that you can, and what more can anyone ask of you?
