i dropped my iPhone 6 and it bent slightly, then went really hot near the top half of the phone; and now it won't turn on... and help or suggestions?

Sorry, but dropping the phone is not covered by the warranty and your only option might be the Out-of-Warranty-Service repair.

You should get the phone serviced by visiting an Apple Store or an Apple Authorized Service Provider next to your place.

Or contact Apple Support to send it in.

If the phone is opened by you or an unauthorized 3rd party, the warranty given by Apple will be gone.

Out-of-warranty repair service

If your repair isn’t covered by Apple’s One Year Limited Warranty, AppleCare+, or AppleCare Protection Plan, your iPhone might be eligible for out-of-warranty service. For example, liquid damage isn’t covered by warranty but might be eligible for out-of-warranty service. Some damage isn’t eligible at all, for example if your device has been broken into multiple pieces. See Apple’s Repair Terms and Conditions for complete details.
