i dropped my iphone and it wont turn on
I dropped my iphone and it wont turn on. I was getting the software update when I dropped my phone. I think what happened was it shut down to reload, as usual, but now it wont come back on. I keep pushing and holding the power button but it doesn't respond. Even when I plug it in the computer, nothing happens. HELP! I'm so scared I'll have to buy a new phone.
iPhone 5s, iOS 8.4
