Hi Applesun,
The first thing to do is talk with your lender & allow them to assess your current financial position.
See what they suggest and they consider getting further financial advice before re-engaging back with the bank.
Ensure all your options are checked, as with the previous comment, is the option to rent the property there?, will the rental income cover all the mortgage repayments or most of it?, so at least you could have this paid for over the medium to long term.
