If income has dropped:
Reduce spending and/or
Increase income.
Simple economics, not trying to be mean.
Try looking at your full household budget. Almost everyone spends on 'wants' that can be cut back on. Those morning coffees/lattes, cable/satellite TV, name brand food items, salon trips, vacation trips, too much house/car for income, etc.
Consider a 2nd/3rd job.
It can be done, might need some belt tightening though.
