Kenna, I'm sorry to say this but - hearing those details - that doesn't sound like an alignment thing, nor a brake thing. That sounds like worn out frontend parts, possibly tie rod ends but probably other parts too. I've always heard/read that if you're going to replace one frontend part, best to replace them all at the same time. A complete frontend job, parts and labor, is ~400+... ouch!
Most full-service high-volume tire stores will do a quick frontend check for little or nothing. They know what to look for and it doesn't take them very long. Pay for a little rack time and at least you'll know what the problem is... or flash that beguiling smile of yours, bat those eyes a few times - and make sure they know if/when you get it fixed you'll bring it to them... if the service manager is in a good mood - might not cost you anything!
