My SO has been out of state on a work trip for two weeks and my MIL has been staying with my kids while I'm at work.  I work three 12 hour shifts, overnight so she's kinda moved in for the first half of the week. 

This morning I came home to my kitchen completely rearranged, and she had also "deep cleaned." I know she did this to be helpful and I appreciate the effort but the thought of someone pulling all the stuff from my counters and cabinets and putting it back in a way that "made more sense" just triggers massive anxiety for me. My home is my space and one of the few places I can feel relaxed because I control the environment. Now I'm sitting here freaking out because all I want to do is put everything back where it was. I'm also a little annoyed because she kept making comments about how badly the surface under my microwave needed to be wiped down and that going forward "the magic eraser will be your best friend." Etc. 

 Ugh I hate feeling like this. I know my anxiety is a little over the top and the fact that I'm exhausted probably doesn't help but now I'm all worked up and I  need to relax so I can get some sleep. What would you do in this situation?
