Dave - I am so sorry for the loss of your mother. As I am sure you know, grief can include so many intense emotions, including anger. Sometimes they make sense, sometimes they don't. My mom died this past March and I was her caretaker as well. I have found that most of my feelings don't make sense. Your anger could be the result of so many things that may make themselves known to you as you travel this crummy journey called grief. Whatever the cause of your anger, be patient with it and yourself. As a caretaker, I have had anger towards my own siblings thinking that even they could not understand. And you know what? Not having been the primary caretaker as I was, they don't understand. As with you, caring for my mom for 3 years was my life. Her passing has left an enormous hole in my heart. It sounds like you gave up so much to care for your mom: other people can't understand your exact experience. Sometimes I feel anger at my mom for leaving me ignoring the fact that she was sick and elderly. I hope you find some comfort in the fact that you gave your mom an invaluable gift...your caring.
