Likely rejecting my kidney transplant and my poor pup is going stir crazy.

I'm likely rejecting my kidney transplant and have been in and out of the hospital a lot. When I'm not, I'm absolutely exhausted. My poor 15 month old Aussie is struggling. We went from doing stuff all the time and structured days, to her being taken care of by my elderly family most days. She is definitely hitting her teenage phase and my perfect calm pup is a tornado of terror, and having unmet needs doesn't help. She is having a hard time regulating her emotions, and is into EVERYTHING (this hasn't been an issue previously). I'm worried that this "time" is going to shape her behavior and habits for the rest of her life. I've been down and out for about 2 months… And if it is rejection, it means long days at dialysis.

Has anyone been through something similar and came out okay on the other side ( I mean with the pup being a chaos queen due to life circumstances). Being so sick has made me extra impatient too, and I feel like such a bad owner. At what point do you consider rehoming…. I can't even believe I'm asking that, but I just feel so bad for my girl. She is just a baby and shouldn't be crated as much as she has to be right now. She gets lots of time playing fetch in the backyard, but I know that's not enough.

I'm so heartbroken, and looking for advice, input or support. I'm not sure I could live with myself if I rehomed.. That's how much I care for her.
