how would i do that?

soo if i do get banded next month, what do i do for when i go back to school in september(im going to be a senior in highschool, and no i didnt fail any years, had prefirst)? I mean for like breakfast, i get up at 5 when school is in seccession and thats when i have breakfast, i get ready at 5:55, leave to go to school at 6:50, lunch isnt usually til 10:32-1:24pm and i wont be having a lunch period because im going to CV-Tec for cosmetology(its like a college you can take during highschool if you like, the school pays for it, its also for anyone else thats out of school too ) and the classes i want to take fill up all my periods and i hate eating infront of people, thats why i skipped lunch most of the time and i know its not good but im embarrassed, im working to fix that, maybe by time school gets here ill be some pounds lighter and more confindent, what would i bring for lunch? what would be good? oh and how would i beable to exercise? i have a job, which i work twice a week and its a cleaning job (yuck) and i might be getting another job so ill be working 5 days a week. I wont be getting home from school til 3:05pm (i would be getting home at 2:30 but do to cv-tec class) on monday's and thursdays i clean from 4-8pm and i want my other job to be on tuesdays, wednesdays(4-8pm), and saturday(10am-4pm) i might get another cleaning job at a hotel or something, so will those be counted as exercise? O.o ugh i cant think of whatelse i was going to say
