Stoicism isn’t a state, it’s a practice. I think the Buddhists act the same way. None of us will ever become truly “enlightened” but if we keep trying we become better ourselves.

I cannot change your emotions or actions towards me; I can only change how I respond to your emotions or actions towards me. It’s obviously way more complicated than that but yeah, you might be a candidate to read some Seneca or Epictetus. Not going to be a cure all but might help you as you navigate this fucked up world.
