Thats NORMAL! The only way to get a job these days is to bang on doors. You have to apply at EVERYWHERE. If there is a business in the building, you put in an application for an open entrylevel position. Be open on the pay also. It helps. You have a few things going against you.

1. you're only 17
2. you're a guy
3. you're desperate

now, 1 and 2 you can't hide or help. But 3 you can. Don't SOUND desperate. Just act like it doesn't matter. Yes, you WANT the job, but if this one doesn't hire you, the next one will.
