My FaceTime won't stop ending and I cannot hard reset it as my turn off button won't work either, furthermore none of my apps will launch or open.

I was declining a FaceTime call when my phone never stopped ending the call. I tried reseting my phone and then the turn off button won't work, it still clicks and moves it just will not do its function. Then my next reaction was to reset through settings, but it won't let me open any apps. It recognizes that I'm tapping it just won't open. the only thing it'll do is allow 3D touch, but you can't get anywhere from the 3D touch. Please help me as soon as possible because, my last resort is to just wait and let it die but its at 90% and i don't have all day.

Thank you.
