maybe the belt came off?
go find a freecycle in your area
http://www.freecycle.org/
maybe you can post for a sewing machine..for free.
also post on craigs list..in your area, "looking for a free sewing machine" . i gave a kenmore away on freecycle. and have picked up fabric that way too..
it is the only thing i can think of, to at least get you sewing again. any neighbors have a machine you can borrow? they may have one sitting around, and they don't sew!
