My iPod 5th gen is not turning on after iOS 8 update!

My iPod 5th gen is not turning on after iOS 8 update! Before this all happened, I noticed that my apps crashed unexpectedly, it was laggy, and it decides to reset on its own at times. I CAN'T charge or plug it into my computer. Also, my home button is sunk in but my sleep/wake button at the top is most definitely not. I know my iPod was not running out of battery and I did not even power it off. I am very disappointed but I really need it to turn on =/

- iOS: Not responding or does not turn on           
Ignore the reset and when it says place the iPod in recovery mode
Place the iPod in recovery mode using one of these programs:

- 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.
