Unless you have given your phone to someone who knows your account details, your phone hasn't been hacked. It's not only EXTREMELY difficult to hack an iPhone it's VERY VERY VERY EXPENSIVE to hack an iPhone. Are you someone who is VERY important on the world stage, like an elected official, president or CEO of a major corporation.
It's possible your accounts have been compromised, but your phone hasn't been hacked. Something else is going on if the screen is discolored. For that schedule an appointment at your Apple Store Genius Bar and show it to Apple.
For possible accounts being compromised, see this --> If you think your Apple Account has been compromised - Apple Support
