Vote, volunteer, get involved
Make sure to encourage and remind any dem-leaning friends, family, etc. to get out and vote!
Also consider volunteering to get people to vote yes on Measure J in Sonoma County California. It would phase out any factory farms in the area and be a major first
One thing that I've found with anxiety that can help is volunteering and other things that help dem turnout. It moves the needle a little and if nothing else it makes you feel productive and some more degree of agency besides just voting yourself
Can find some phone banks, canvasing, and text banks near you
Also another small thing that can also help is reminding and encourage any dem leaning friends, family, etc. to go out and vote. Helps more than you'd think
