Lisa,
We have another member, her name is Juliann, she also has a parent going thru similar circumstances. Look for her posts as we have been guiding her, trying to help. Juliann is 30 and her mom is 69, she has sisters and they are all in the same boat as you. I think most important is to remember she may be cranky and not herself, it may be because of her pain or just a side effect from dealing with this disease...how old is your mom.? I IMAGINE HAVING 4 KIDS OF YOUR OWN ITS VERY HARD FOR YOU TO KEEP AFLOAT!! And have a sense of humor too...as you have to when you have 4 kids..I always say take help from others if they ask, any friends, relatives who live near by, and take time for yourself, keep the kids on their schedules not to make them think things are unhappy and sad just different. I am waiting for your answers on bladder removal, if that was an option or not. and the results of the petscan..until then Ginger
