I'm really sorry to hear that you're having problems with your iPhone. It must be really frustrating!
Your phone may be in desperate need of a charge. Leave your phone plugged in for at least an hour. I would also suggest gently cleaning out the Lightning port on your iPhone, as sometimes dust and dirt can get trapped in the port and hinder the phone's ability to charge.
You can follow more detailed step-by-step instructions from Apple to help you here If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support. That page really outlines basically all the ways to help you get your iPhone up and running again.
I really hope you get this issue resolved! Best of luck, and hope this helps!
