Can I Lower My Mortgage Without Refinancing?

refinancing

When we bought the house 3 years ago there were two incomes coming in, now we just have one income and the savings are gone. I have excellent credit, but my cc’s are filling up – I do not want to hurt my credit, but am pretty close to being paid in some distress. What can I do to lower my mortgage to get back on track? Would I have to refi or is there any way my current lender can re-adjust?
