The action that leads to security and a better life for yourself and those around you is to organize your community along whatever lines are possible. Unionize with your coworkers, form a tenant's union with your neighbors, physically get out in the street and provide security for LGBT+ events and spaces. Build up parallel structures so that when the government fails, you and those you care about will still have access to food and water, a place to live, and security. Join a political organization that's active and actually does things in your area (one of the communist parties, DSA, or even just Food not Bombs) and do all you can to prepare for a revolution that might never come.

I'll close this by saying that I've been harsh on voting and the electoral system in general during this conversation, and probably too hostile in tone towards you. I apologize for that, because it's sometimes hard to tell when someone is actually acting in good faith, this being the internet and all. Voting isn't something I think is particularly useful, but if you vote for the democrats because they're less openly fascistic, that's up to you. The key is to not let your political activity start and end at voting, because direct action in the real world is by far the best way to achieve positive change. I wish you and yours the best in surviving the collapsing fascist hellhole we find ourselves in.
