Sanity seeker, Here is some relaxation and some hugs for you
I am sorry you are in such a bad place. I am hoping that the wind will stop so that you can get the relaxation and space that you need.
Take care of yourself and don't push yourself past what you can do.
If you can't face the mess of papers, could you ask a friend or you son to throw it all in a box to deal with after you get through your ex's visit?
