Hi Victoria, I am sorry to hear of your medical issues and the situation that puts you in with your hosting.
Firstly, go to your listing editing page and 'Snooze' your listing! This will remove it from search results which will give your explanation more credence with CS.
Omce you have done that, phone Customer Support on......... 02 85203333 (that is the Sydney number) and explain your situation. You won't have to go into medical records but explain that hospitalization will require your listing to be out of action for a while.
CS will relocate your existing bookings or refund them and there will be no black marks against your name.
All the best Victoria I hope all works out OK for you!
Cheers.....Rob
