Can I amend a discharged chapter 13 to include my home

[Reginac]

I excluded my home in 2008 when I filed and have since been discharged, but right after my husband lost his job we were struggling and facing forclosure. I have a 1st and a 2nd mortgage. The bank modified the first but they say we dont qualify for the 2nd and we are behind 23 payments on the 2nd. I dont see how theyve helped since they can still forclose due to the 2nd? so can i go back and amend to include the home so i can give it back to the bank? Im afraid if I walk away they will come after me for what is owed.....FYI we are current on the 1st due to the modification
