Jim, I think you need to ask yourself a couple of questions: What would happen if you were to drop dead tomorrow? How would they manage? I am sure they would be able to find someone to take on the website. Remember, no one is indispensable. Second question: What is more important, your friends or your health and wellbeing. If you answer these two questions truthfully, then you will have your answer and know what to be doing. If they are good friends, then they will completely understand. Good luck with whatever you decide.
