It is probably to late to respond, but I would say you have 3 options
1: Work, work: Just work really hard next year at school, get many roles, make that resume pop. That will help you next year.
2: Look around: Just keep looking. I don't know many sumer stocks so I can't be of help here, just keep looking.
3: Rise up: like a ferret weasel your way in doing tech and perhaps it will lead to something onstage in the theatre. Better to be working in a theatre than Walmart, right?
I appoligise for any spelling mistakes. I may be on my mobile. Clumsy fingers and small little touchscreen keys don't mixx. I try to spellcheck, but I may miss something.
