What do I do? This is unfair to this woman

I was taking care of a woman with Alzheimer's and not to pat myself on the back... I gave this woman 100%. But other caregivers did not do their job young girls did their homework and other things. Then left this poor woman in a soiled depend for the next shift. But things got even worse the patient started passing blood and a clear liquid from her rectom, bed sores, and bruises and no one knew how or why this happened. And when I brought all this up to her daughter and logged it in on my shift work she had enough. And she told me I was no longer needed.She thanked me for taking such good care of her Mother she addmitted I kept her clean and other family members praised how good she looked and smelt when I was there and cared for her.. After doing my job and doing it 100% it was not enough I am sick over this because I loved and cared alot about this woman . Now I am afraid for her well being... But what can I do? This is so unfair to this woman .
