I feel like a sitting duck

I'm finding myself getting more and more angry each time I find more news about Trump turning this country into a dictatorship. I want to do something, there's something screaming at the back of my mind telling me I need to do something but my issue is that I don't know exactly what that is. I have a family, I'm raising two small children and I'm terrified of their future, but it's not like I can just drip them off with my mom and set off on an aimless mission to fight fascism. I don't know of any local groups coming together, America is so big and divided that I feel like there isn't enough of us to get together to rise up like they did in the European countries. My friends all tell me they think I could be someone who can motivate a crowd to fight back, but where the fuck would I even start? Maybe I'm just letting myself get too overwhelmed to think straight, but what can I do? I'm looking for genuine advice, I don't want to give up
