Surviving a bad boss

Hi Brooke, I am in a situation where I am trying to manage my experience with a leadership that uses fear as a motivating tactic. I know that how I think about the situation, will determine my experience. I also know that I can chose to have whatever thought I want about the situation. I would like to think thoughts that make me feel safe, but the environment does not support this. How, when external circumstances dictate the opposite of what I want to experience, can I create a different reality and make it feel real?
