Ah, I was in your shoes last year, except no SAT.
It's better to just relax about your testing. If you do bad the first time around you can always retake them. They will always take your highest score so don't fret. Besides taking tests stressed never helps! A couple of my friends were stressed the first time taking it and it reflected in their scores. They eventually retook them and since they were more relaxed about it they got the scores that reflects their test taking ability. The ACT was easier than I thought, too.
You'll also find that college isn't as expensive as you think! I was surprised when I started looking into one of my favorite private college and freaked at the 42K/year price tag, but in total with aid, scholarships and the FAFSA, I don't even have to pay much other than books, supplies and like $1000 a semester. You may also find you change your mind. Lots of people did that this year especially after going to visit. Idk if you've gone or not, but it's a very valuable thing to do.
I also wouldn't be worried about dropping off your applications. Trust me, there is nothing weird about that...that referring to being responsible and trying to get a job for the time being. If it turns out though that you don't find a job (because I've recently been applying everywhere with no bites), you should at least volunteer somewhere. Volunteering goes a long way, especially with scholarships and college applications. Whether it's church, animal shelter, library, etc, etc it all looks good on paper. Or even working around the neighborhood is very good too, babysitting, housesitting, petsitting, as unappealing as it is mowing lawns. At the end of the day, money is in your pocket.
Good luck. :) Don't stress out too much, it all gets better. PM if you want to talk about anything too.
