I hate when my phone is broken

I dropped my phone a couple times but it didn't make my phone broken, just a scratch. For a month i didn't dropped my phone again but i see a tiny space from the back(mirror) like the mirror is almost fell off from the body, and i dropped my phone when i'm in bathroom into a bucket full of water. I know my phone is water resist, but when i took my phone up i see water from the camera (front&back) so i think my water resist is breached.
