Shortage in Escrow-doubling payments

We just got a letter in the mail stating we have not had enough in our escrow account for the last year. Now we have to pay almost $8000 in less than a month and still have our payment go up by almost $500 or dont pay the $8000 and have our payment more than double from about 1220 each month to 2500 each month. there is no way we cand do either option. We dont have $8000 sitting around and cant afford the double payments for the next year to make up on escrow. We also cannot refinance because we have claimed bankruptcy. Are there any options for us??
