I feel so guilty it's making me nauseous

My SO and I are having to move out of our apartment because of toxic black mold being in the air vents. So we are putting all our stuff in a storage unit and living apart for 1 month due to work related stuff.

Where I'll be staying I can't bring my animals with me, so they will be staying at his mom's house. I'm not worried about my dog as much as I am my cat.

Dallas (my cat)is my baby. I love her so much..I think about her all the time and we have a really good bond. I'm so worried about her going to his mom's house. It's a completely different enviroment. She doesn't like dogs or other cats...and she doesn't like children . She can not go outside because she is declawed and can not protect herself.

I'm so scared that my MIL cat will attack and injure her. I'm also worried that when my step son goes over there he will harass her like he does my dog. (He is 5)

Poor Dallas...she is going to be so heartbroken thinking I abandoned her..

I don't want her to resent me!! I feel so guilty it's starting to make me sick
