You ask, "my house is being foreclosed on.am i responsible for the balance if the auction sale price does not cover the loan amount?"
The right answer is, "yes and no..."
You are in fact responsible for the money you borrowed and apparently are not able to repay. And if the bank or mortgage company can, they will ask you to sign documents to remain responsible until their loan is satisfied. (I suggest that you engage a lawyer to review any paperwork they ask you to sign.)
But apparently you have reasons why you are not making the payments and so they are foreclosing on your home, meaning they are taking the title (true ownership) back from you for non-payment of the obligation. Once they have taken your title and ask you to remove your personal property and your residence to some other locale, you are probably no longer responsible for the loan. What comes with this however is that they will review your finances to see if you may have assets that they can attach--to get the money they believe you sill owe them.
So if they found that you have a yacht or some other asset that they can put a lien on, of if they find that your spouse is a doctor or lawyer or a movie star or professional athlete and earning a good salary, yet you have not made your payments, they can chase you for fraud.
In fact, if you are only telling them the truth, and you can't make the payments, then the foreclosure and auction will probably free you from the title to your house and your responsibility for the loan. Also you will forfiet your acceptable credit standing for some years.
If you want to stay in the house and think that with a mortgage modification you could afford to actually make the payments, talk to a lawyer who specializes in bankruptcy. A simple bankruptcy will delay the auction for up to 6 months, and a loan modification may lower the payments by changing the rate, or the balance owed--if the property has lost considerable value--or the length of the repayment term. Banks are not usually willing to be generous in these matters, but often will give you some additional time.
