Do I qualify for a mortgage mod?

I have a 80/20 loan thru GMAC Mortgage...the 80 is a 7.25 rate and the 20 is a 8.325 rate..my ex fiance recently left me and its hard for me too afford the payment..I'm usually $200 short every month. So I'm thinkn if they reduce my rate by 1.5-2 percent thatll save me $200 a month...I've tried to contact them and they said they have all the info and are working on different programs and may take 2-3 weeks. And my loan is owned by fannie mae..I'm really hoping they'll help me because I'm digging myself a deeper hole every month and my credit cards are gettn alittle ridiculous now...
