Because my mother was 96yrs old means there is no respect for her in the law when it comes to med. negligence? I need help pls.

My mom went into Cedars Emergency Sept 2008 with pancreatic infection & was told that most people even-though those that are forty do not survive that infection .. well my mom did although she had cancer and was getting chemo for it prior to her entry into emergency which they said her body was reacting positively to. Subsequently my mother contracted another infection in the hospital (C-diff) and although I requested that the hospital do all that was possible they did nothing because of her age and the fact that she had cancer . My mother was not fed intravenously for over eighteen days and did not have water for forty-eight hours THIS IS PLAIN OLD NEGLECT-!! and WAS A HORRIBLE WAY FOR MY MOTHER TO DIE, MY MOTHER DIED NOV 20,2008 I was at the hosp. daily and witness MUCH NEGLIGENCE
