my phone won’t turn on or charge after the off button has been hit too hard

so basically this happened before i was running and my phone fell out of my pocket and i think a rock hit the off button too hard and it just turned the whole phone off when it was at 30 percent , i left it to charge over night and it turned on no broken screen or anything, this happens again but my niece tries to grab my phone but i snatch it away from her but she holds onto my off button too hard and the whole screen goes black again i tried charging it overnight again and it’s not turning on, i trieed pressing the buttons and everything and it wont turn on
