What can I do about Trump?

I am just a third year teacher, who loves my cats and my friends and wants to be happy and safe and feel confident that my trans family members, and undocumented students can live a happy and safe too. Donald Trump appears to be starting the rise of MAGA total control and it feels surreal. As a Texan, I feel helpless. I want to take direct action, but what action is there to take? I’m so lost. I don’t want to see our country fall like this.
