GAH!!

Do you ever have that thing where your really annoyed because something happened, and that moment when the good thing happens? That's what I'm waiting for now. You see, a few minutes ago, I was watching Charlieissocoollike's Comic Relief Video on my iPod. Now, shortly after, I left my iPod alone for a bit and the screen went black, hinting that it had gone into lock mode. I then tried to unlock it a few seconds later, but it wouldn't go onto the lock screen. The screen stayed black. I thought that maybe it had turned off, (Which is impossible, because it was on a full charge) and I came to my laptop and plugged it in. It still won't turn on. Now I am slightly freaking out. Does anyone know how to fix this problem??
