It is called "quality of life"
Mary, the one thing we CAN do for our pets, when it is time, is to allow them to leave this world in a rather comfortable state. We cannot do that for humans. If it is her time, and only you and Puddy know that, then allow her to have peace. She doesn't sound happy to me. I could be wrong.
Anyway Mary, we will all support your decision. You have my nod to allow Puddy to be at peace with her illnesses. We are all going to go.... it may be her time.....
