Am i eating enough?!!!!?

Mmk...so, in the morning (on a school day...monday-friday) i eat: a light little breakfast....NOT MUCH AT ALL. and the reason i don't eat that much is because i have athletics in the morning so i don't wanna throw it all up! like, this morning i ate two oreos and i drank a sip of water. THEN when athletics was over i went through all my cles....yada yada yada...and finally lunch arrived.....for lunch you have the choices of: HOTT LUNCH, SALAD BAR, SNACK BAR, AND HAMBURGER LINE. i usually eat the hott lunch....(it's whatever the cafeteria wants to serve that day)....today, i ate hott lunch and got: a chicken-fried steak, mashed potatoes w/ gravy, a fruit punch and two whole wheat bread rolls. (it was gooood!) LOL anyways after that i go onto fifth, sixth, seventh, and finally eighth period. After eighth i get to go home at 3:45...when i get there i eat a snack that'll hold me up till dinner which is around 6 or 7. then at dinner i eat whatever my parents give me basically! LOL tonight i had two slices of pizza (since it's friday.) sooooo that's basically it.....tell me if i need to eat more or less! thanks!! -daisy.
