Talent (-less)

Have you ever just picked something up and said, "I'm gonna do this for talent show!" Ever found out that it's really hard and you only got a week? That's how I feel.
Let's be up front, ok?
I do not play guitar. Sure, I play percussion and piano, but guitar? Nope! And then I decide to go on YouTube and look up "Blink" by Revive and try to sing and play guitar for a talent show! Good job Annie! So I basically have a week till the show and I have to learn it all within that time frame, because either that, it's a NoGo. My fingers have almost been rubbed raw and I just am starting today. How am I going to do it? I have absolutely no idea. Any hints out there?
I will try to get where everybody can comment by the way. If you find that you can comment, and you want to comment, (because I know there are people out there reading this who don't want to comment) then go ahead and give a shout out! Whatever you want... well, except for negative stuff like "you suck" and all that. (Because I totally don't need that bogus.)
And by the way... for all the diabetics out there in the world. Thanks for stayin' strong! I know it's hard, but put some humor in it, and like some would say "suck it up" because it's not gonna get better if you're moping.
From the All Randomness,
