should i work with second or wait until first is done?

i am currently trying to get a loan modification. last year i filed chapter 7 bankruptcy. i had a first and second mortgage after the first fell behidnd i was instructed to stop paying on the second. i stopped last august and was told give up. well with all of the new ways they are working with people they are trying to save and lower my first and lower my second,. they want me to call and set up some arrangements, i do not want to do this until i know what ios happening with the first but i can only afford the first if they lower ther second or it would really help. should i call?
