Donna,
First, you need to decide whether or not you can financially afford your mortgage payments. If yes, the easiest way is to just bring your loan current by paying the missed payments and late fees.
If you don't have the cash to bring your loan current, but you can afford your mortgage then you can ask your lender for a repayment plan. A repayment plan allows you to continue making your on-time monthly mortgage payments along with the missed payments and fees spread out over 12 months. Your mortgage payment will be higher for 12 months until your past due is paid. Your bank may ask you to show them that you can pay this amount.
Second, if you can't afford your current mortgage payment but you can afford a lower payment, you may be able to negotiate a loan modification with your lender. This is typically harder to do then a repayment plan. You will most likely not get a loan mod if the bank can recover their loan through the foreclosure process.
All of the above depends upon you working with your lender to negotiate a win-win that both can live with. You will need to be persistent (but pleasant) and don't be afraid to ask to speak with a supervisor if you are getting the run-around.
If you can't afford to stay in your home then it is time to sell. If you are going to sell, the sooner it is on the market, the sooner it will sell. If your house is in very good condition (based on buyer standards) and you can list it below market it may sell in time. Otherwise, you may want to consider selling to an all-cash buyer or investor.
