I'm in high school as well, and I know exactly what you mean. Once the shows over, you're done. It's not like you go and find another job, you actually have to wait around until the next season show or if it's the last show of the year, until next year (unless you have a summer program, of course). This is when I usually take a week or so to just recover from the chaos of High School theatre, and simply relax. Because as much as I love stage managing, managing 160+ students as a peer is challenging.
Then of course, I try and focus on my grades. Which take quite a blow when you're working until 8-10:30 for two months straight. And then you find yourself submerged once again in a whole different kind of work.
