How do i balance school and a diet?

im in highschool, i'm 15, 5,7 and 139 lbs.i was 136..but had was over at a friends birthday and of course there was nothing healthy to eat. only cakes, pizza and hotdogs.so i gained it all back.. i just started school on monday and i have been at the same weight since then. during the summer i would eat small snacks thorough out the day to kept me full.now i am only eating three times a day.i eat special k's cereal (strawberries) and half a banana for breakfast. around 12:40 or so i eat a banana (usually) or crackers and cheese. and maybe one or two french fries from my friends, just so i know i will have enough for the day. then at 3 i would have crackers and peanut butter, and at 6 i would eat my cereal again. (or i may just eat cereal at 3 and that be it because i get pretty full fast)i know for sure this is not all the calories i should be gettingbut i have no clue what to doi can't eat anything in class because it's not allowed..plus i walk a fast pace every night for an hour around 7.still not losing anything :(any tips on what i could do? i desperately need this...
