She Has Been Very Sick For Years

My mom was in a comma for no apparent reason about 5 years ago.  She came out of that and seemed to be fine for quite a while.
The next year she started getting sick a lot.  She spent a lot of time in and out of the hospital for the next year or so, before they discovered that she had stomach cancer.
They operated, and said they got it.  But about 2 months later, they said it was back, but it went dormant.  It was not in remission.  It was still there, just not growing or going away.
She also did something, in that same time period, to cause two hernias.
The Wednesday before Christmas, 2010, she was put into the hospital to have surgery to repair them.  Something happened and they were causing a septic infection (?).  
Anyway, the doctors are saying that she has to have someone in the room with her 24 hours a day to watch her, because she tries to sleep walk, and she doesn't have the strength to stand.  So they are worried about her hurting herself or something.
