have the wheels come off again?

I don’t know how she copes. I don’t know how she keeps going.
Wednesday she had surgery to replace her ureter stent with a bigger one. Surgeon said he lasered something but he lost me. 48 hrs later she’s showing all the signs of infection except she’s on antibiotics now. She’s cold and shivery, her flank aches and while her temperature is acceptable at 37.8, it’s creeping up to dangerous zones.
Ive arranged for someone to drive her to hospital if need be so I can stay home with 11 wk old puppy. If I have to go in puppy will come with me, scream all the way down the highway, we’ll drop her off and come back home. But it means I can’t take anything to help me sleep. I need to be alert for whatever happens.
That’s my life. Always on alert waiting for the next wheel to come off. Caregiver burnout is very real.
