You said you are able to pay bills + extra every month? On just your income? If so, you can file bky Ch 7 ("straight liquidation"), re affirm on everything except the line of credit. BUT, since that LOC is secured by your home, you may have to file CH 13, where you pay to the trustee and they pay your bills. It is much easier to recover from a Ch 7 bky, which makes NO sense, as you stiff most creditors; than a CH 13, where creditors file against you and you have to repay at least part of those bills, over 48-60 mos.
Unfortunately, in cases where you are trying to "save the house" the Ch 13 is usually the answer.
BTW, even though you will be contacting the attorney tomorrow, it will be at least a week, likely longer, until you actually file. Your attorney will probably time the filing with the 30 days the back gave you to pay the loan, so you can get the best benefit of the automatic stay once you file.
Good Luck!
