What do you do when you are nervous?

I eat A LOT when i'm nervous.

It's weird, though, because i'm stressed a lot and only weigh 115 pounds.

I don't even exercise. ._.

I sing the nyan cat song

I keep moving my leg like up & down or I shake. but I never bite my nails or stuff like that.

twitch no idea why

sweat like hell, and eat a whole crap load of food :\

Eat junk food or bite me nails.

bite my thumb and i blink alot
