Sorry you have all this on your plate. That's an awful lot. It's good you can take a day tomorrow, I hope you get a chance to relax a bit. Taking care of yourself and your family first is most important. I hope you get some answers about your MIL.

I have an alcoholic father and have had to deny him access to my home and children before too. I understand how difficult it is. Having definite boundaries with those types if people really helps I've found.

I hope things look up for you right away!
