You do you but I joined a union, started volunteering more, have gotten more involved in my various communities, and am actively trying to have more fun in my day to day. Think of the beach scene in Camus' "The Plague."
Times are bad. We will outlast them and build a better future together.
I wouldn't tell anyone else how to think or feel, but I will just say that, for me, the only way to stay sane after the 2024 election has been to pretty much abandon hope. The US is cooked. Everything I value about it is doomed. We're heading into a long period of dissolution & chaos.
