haha i have the EXACT same thing, although it runs in my family, i don't know if it runs in your family too, but i think it does. its called hyperhydrosis. it means that you have either too big or too many sweat glands on your hands and feet.
actually, my hands and feet are soaking right now, it unpleasant, i know. :(
you should go see a dermatologist or a skin doctor and he might give you something to rub into your skin to decrease the sweating. i use Drysol, it kinda helps :P
