I am gonna scream!!!!! 😡

My MIL has been here since 5:00 p.m last night (it is now 8:46 a.m) and she has done nothing but complain and throw around orders since she got here. We live in her old home and have been doing fixes for the year we have been here and she says we have to replace her roof and deck before she takes the house back next summer. We have to fix her yard. She says when she comes back that my husband and I have to come out and help her fix everything and do yard work. She will be rebuilding the garage and says we have to come move everything out of it for her and help her rebuild it. She is saying that my husband will be spending Christmas with her and won't be coming with me to see my side of the family. We normally split the entire day between my family and his and she says he will be with her all day. She then said she wants to get to know my family so I invited her to our family Christmas party but she came up with like 3 different excuses to get out of it. She was also talking shit on my mother. Yes, my mother needs to get her life together and stuff, but it is not my my MIL place to say anything about it! I am so freaking sick of her already and it's only the beginning of her visit! She is also mad that I can't come to lunch with her and his family on Thursday. I have to work. That's also the problem with her demanding we do all the work at her house. My husband and I both work and are going to try to get a mortgage for a home of our own and don't have the money to pay to fix her roof and deck that has been falling apart for years now. We have only been here 1 year. The roof and deck have been falling apart for at least 4 years. Her brother will be moving here with her and living with her so I don't see why he can't help pay to fix things and get thing's down? It is not my husband and I's job to do everything for her!!
