Daniella,
Moves are high on the stress chart. You have moved so very much. Try actually living in your new place slowly. It's hard to part with something that is familiar and safe, especially with health issues. I'm struggling too dear and I have my husband. Course, I've also got 3 little dogs. More stress. Why not wait to really live in your place until after you have the surgery.

Hugs to you
Billye
