how do I get my apps to go back the way they were?

My boyfriend decided to put all my apps in alphabetical order on my phone! I have a Samsung galaxy 6. How do I make them go back to the way they were before? I hate it like this! I had everything memorized and now it's like a new phone! Very frustrating! Any help I could get would be appreciated!
