Work probs, and now I get an insurance denial

Today was an incredible horrible day.  First I am looking over stuff done while I have been ill and the amount of errors is unimaginable. I get home only to find out my insurance has completely denied my hospital stay. I was there 8 days with IV's and all sorts of tests. Finally, it came out to be MS. With the way I felt,I certainly cannot sign myself out. AMA..my doc would have protested.   Even after I was discharged, I was still unable to walk correctly. Using a walker, and completely unbalanced I struggled at home the first couple of weeks. Now my insurance feels this entire stay was completely unnecessary and I could have been cared for as an outpatient. That is soooooooooo not true. I had so many issues.  But, why am I kidding myself again.  I did have emergency gallbladder op, last year in fact, and they thought it was unnecessary then. Maybe I was expected to have that preformed at home, or in the doctors office. Yeah right, I'd be in a box right now, about 6ft underground. Insurance really makes the sick fight  for coverage. All these years prior I didn't need them much, now that I  do, they deny me the benefits I paid for.  They have got there premiums for over 10 years. And that's more than they have paid out.
