Somehow I messed up in my description. We deal with the person at meetings and classes as best we can. We are going on a four day retreat and she has signed up to go. In meetings and in classes she asks the instructor to come and help. If they can't then she pesters/bugs/etc. the people around her to help her. Sorry for not making myself more clear.
It is not our intention to be rude to her but we really would like to get the point across that she has to take care of herself and not expect others to stop and help her. Which ordinarily turns into doing most of it or helping her remove stitches.
