So what did your mom say when you “had it out” with her? Did she understand that you’re exhausted and can’t keep this up?
Here’s my suggestion, and I’m actually not being facetious, although it may sound like it: introduce your mom to the God of Wine. Many years ago I had a pinched nerve in my neck that no medication could touch. The only way I could get relief was to GET DRUNK EVERY NIGHT until my dumb-a$$ doc finally referred me for physical therapy. (God bless physical therapists!) It was the only substance that allowed me to sleep at night.
THAT being said, I personally did not feel as though I should rouse my significant other to "walk the floor" with me during those times I was in pain. My SO had a job to go to in the morning. I'm sorry your mom is in pain, but it sounds like she's being awfully selfish here.
