My iPod Touch 5 Will Not Turn On... At All.

Question

My iPod touch 5 will not turn on.
It's not that it's dead, nor that I turned it off.
I left it on, wrapped my earbuds around it, plunged it into my backpack and headed out... In the rain.
I had an otterbox case on it too.
I come home, leave it to chill out before using it for about 20 minutes because it's also very cold outside. (15-20 degrees fahrenheit)
After 20 minutes pass, I need it for something. I try to turn it on, and nothing pops up.
No apple logo.
No empty battery photo.
Nothing.
I tried plugging it in in a variety of different wall plugs and computers.
Nothing.
iTunes doesn't open, iPhoto doesn't, nothing.
I don't want to reset it completely because I would lose over 1,000 photographs and memories.
I don't even know HOW I would go about resetting it considering it's not working.
So much for a "protective" case.
It was in a backpack, an otterbox case, and I was outside for about 2 minutes in the rain. I'm not sure what to do.

Plave it is a sealed container with uncooked rice for a couple of days. Then:
Try:                                               
- iOS: Not responding or does not turn on           
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable              
- Try on another computer                                                       
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

The above my erase the iPod. If you do not have a backup contacting a data recovery company may be in order. Not cheap.
