Still processing...I

What a month February was .  It started normal but ended in a way that changed normal forever.

I spent part of the first week of the month in San Antonio for work. Since I work part time and worked on a day that isn't a usual day, I took the following Wednesday, the 12th off.  Mom had back surgery in Houston on Monday, February 10.  It was for spinal stenosis. Her back pain has been so bad for several years now. She walks hobbled over with a walker and just hurts all the time. 
I drove into Houston on the 11th with plans to stay until Thursday just to help them out at home after the surgery.  She was sitting up in the hospital bed all dressed and in good spirits when I arrived. She had walked twice that morning and they were ready to dismiss her.
That day at home she walked the most straight I have seen her walk in three years.  She said she was sore but the pain was less.  It was a low key afternoon at the house.
Wednesday she continued to say her back was sore but the pain was less.  She walked a little stooped and seemed a little tired but nothing out of the ordinary.  Sometime during the day she mentioned that she was having trouble emptying her bladder, and I said something like, "oh, you need to go to the bathroom," and she said, "no."
We discovered that the big freezer was broken and not cooling, so Dad and I toted all the food over to the neighbors, Bill and Terry.  Mom cooked up some of the cookie dough cookies that had been in the freezer.  We all went to bed.

About 7am on Friday I woke up and could hear mom & dad in their room. They are not early risers and I got up to go see what was going on. Mom was shivering. She was so cold. There were at least five blankets on her and her teeth were just chattering and she kept saying, I'm so cold, I'm so cold. 
I got in bed with her to see if I could warm her up but she wasn't cold.  I found the number for the Humana nurse and called. They asked how long the symptoms had been going on and dad said about an hour. The nurse told me to call 911 because after 30 minutes they get nervous about sepsis.
