Carol,
You have to decide on this one! It is your health and well-being that you
have to think about. I am sure you would love to play for the couple and
fulfill their wishes but you health is more important. I would not punish
myself to play when there are several others who can do it and who are much
healthier. Do undo all you have worked so hard to do. I am praing with you
and trusting the Lord to lead you to the correct decision.
Ned
