Hi GrandmaJean, first I hope your appreciative of the fact that a lot of people don't have anyone to help them, go to treatments or help with anything, and they might have family around, but they just don't help! That's sad. But I do understand, I have this little "tic" inside me, that when I want to be alone, I want to be alone! Telling her could get tricky, when you decide to do it, please take it easy, be thankful for all her help, and maybe use yourself as the excuse that she needs to go now because your "feeling guilty" for taking all her time, etc. I'm sure she us just worried about her sissy and wants to help. I had family that just about smothered me, I had to ask them to not love me to death.
I'm happy you have such loving and caring family! Go get the rest of those treatments and finish off that cancer! Let us know if you need help with anything around the site.
