You have been tensed about something from a very long time and right now you cannot think of anything else.
You are just waiting for something to go through and you are already thinking about what you are going to do after that. What if the thing you are waiting for does not get through as planned? What if your expectations are not met?
What if the plan that you thought through and rethinking about, changes aspects over the next few days while you wait for everything else to get along?
This could be the time that you wanted, or rather the timeout that you wanted from work but you are wasting it on overthinking. Just calm down and relax until everything aligns.
If it is in your control, go ahead and just do it, if not, what’s the point of making detailed plans? It is time to take a day off.
