I was talking to my sister the other day and told her that I don't want my children to take care of me like I am taking care of Mom. She asked me "then why are you doing it?" I didn't really have an answer.
So, why do we (you) do it? I think the main reason I am is because my Daddy did it and while Mom needs someone with her 24/7, she still has her mind (99.9% of the time anyway, and we have noticed a decline) I am not ready to place her in a nursing home. I do have great caregivers for us during the day, and care for her every other weekend in order for me to spend time with my family and have a life. Are there days when I say "Screw it I am DONE!"? You betcha...but then I "get over it" and go right back at it.
