Katie, if it makes you feel any better I'm 45 and I dropped mine in soft sand on the beach and this happened! They aren't very durable cameras, sadly. I'm a mom. If you can't fix you can show your parents this so they don't think you're an irresponsible teen ;)
The only thing that has worked is to gently grab the lens, pull it out as far as it will go until fully extended. While keeping it extended turn the lens to the right until you hear a click. Once you hear the click, release the lens and turn the power button on and then back off again. This should take care of the problem. It hard to do, but keep trying! It sounds like an awful thing to do but I decided that if it was already broken it was worth a try and it worked!
A word of warning. ALWAYS make sure your fingers do not touch the front of the lens when you power on the camera. Even the slightest bit of obstruction seems to make the problem reoccur. Another note. I had tried this several times until I finally heard the click, so please don't give up on it, just keep trying. This will work and it will save you a lot of time and money having it fixed.
Sadly, every time I forget and use the zoom function this happens again. It's getting harder to fix every time. A word of advice is not to use the zoom anymore. so this doesn't happen to you again.
