When I was in a bad place, I had a black friend who would always tell me 'I see you <deadfred>' and 'keep your head up'. Do that. Anywhere where you can be a feedback loop to give others a little support, a little strength, a feeling they aren't alone is huge.
Don't post negative if possible, that adds to their maximal pressure on society to look like they are winning, that supports them and their narrative. Post about your grandparents overcoming this stuff. Post america rejected it before. Post a small act of defiance you did, instead of conforming in advance. They will mock you, because all they have is mockery and pressure to conform to give the illusion that everyone has given in, that they have won. Their mockery is weakness. Is admitting they don't have control.
These people only win when we give up. It's why the have maximal pressure everywhere. In the hopes it overwhelms us and makes us think they have already won.
