Dropped iPhone

My phone fell from the third floor in my house to the first.. a modern tragedy. It didn't shatter which I was hoping for, but it would not turn on. I found a video about a hard reset and it worked.. until the screen cut off again. I did the reset once more and it seemed to work for about half an hour before it cut off again but this time it is completely gone. I plugged it into my Mac and everything. It still will not show any signs of life. I don't know what to do and all apple store near me are closed due to the corona virus.. does anyone have any advice??? I will try anything!
