I'm glad she's on the road to recovery, Beth, even though it's going to be a long one.
My Dad didn't like being in rehab one bit after his surgery and made it known
loud & clear every chance he got!
But, he saw how much it was helping him so we all toughed it out. It's so hard when they won't cooperate. He didn't like being alone, either, so we all had to put in hours there with him to keep him company - and out of trouble!
I was working at the time so it was a delicate balancing act to say the least.
I hope things are back to normal (or as close as) for you soon. I'm saying a prayer for your MIL and for you and your family, too!
