Why am i so jittery?

Everyone tells me that i move around a lot. I cant sit still ever!! what is it??

It depends... perhaps you just have too much adrenaline, or many other things. It could be ADD, ADHD, etc. But if there are no symptoms of it, you may just be used to it and have too much energy that you need to burn off. Most people use this technique while they're eating to burn off the food they eat. For you it may just be that you're not tired enough during the day, try to get yourself more tired so you don't have so much energy. You could try working out first thing in the morning, not drink coffee, anything that reduces your energy level.
