I understand. My what if machine only spirals in one direction, negativity. For positives it’s very conservative. For me the most effective way to get past it is to tell myself so what. If things get bad, well they get bad. I’ll accept it. I’ll do what I can to make sensible decisions and deal with what ever happens. It brings some relief to give your self acceptance/permission to just do what you can, and whatever will be, will be.
