So stressed that I’m sick!!!!

I am so stressed out that I have made myself actually sick! Tomorrow my Mother in law will be here. The home she’s coming to take back is a disaster area. The yard is even worse. Her cat and my animals are gonna fight. She’s gonna bitch about everything the entire time. She refuses to stay anywhere else. We can’t afford to stay in a hotel room. We are in the process of trying to buy our home and move. My job and my husbands are very stressful jobs. We just don’t get a break for the next few months. I don’t know what to do, but I’m physically nauseous and want to throw up I’m so stressed.
