I am intemidated by the foreclosure and by First Horizon

I am behind on mortgage payments due to job loss 7/2/2007 and separation/ divorce with my wife no longer contributing towards home payment. I was only 2 months behind when I entered information for consideration for First Horizon's workout program on 10/1/2007. It took First Horizon until 2/20/2008 to respond and deny my work out package. During that 4 month window they would not except any payments toward the mortgage. Thus, I am now 6 months behind and my taxes and escrow is all screwed up so my monthly payment went up $300. They are now demanding the total amount owed on the house and have notified me through their lawyer that they have begun foreclosure proceedings. They have not returned my consistent contacts for over 3 months. I am trying to sell the house and have had it listed on the market since 9/1/2007, however, it has not sold yet. The house is in great shape and should sell this spring. I do not live in the house as I had to move to FL to attempt to gain employment. I do have a renter ready to move in and pay rent equal to the mortgage amount until the house sells. I am hesitant, and intimidated by the foreclosure.
