I deleted all albums from apple music library, this deleted all of my saved songs

I thought it was ridiculous that saving a song to a playlist shows the whole ALBUM as in my apple music library for some reason (only for it to include the specific songs added from that album; nonetheless it's stupid). So trying to fix this I unchecked both "add songs to my library when I add to:" options, and then deleted all my albums thinking, hey, if this somehow messes up everything at least I can click command + Z and everything will be back, right? WRONG. Now ALL of my songs are gone from ALL of my playlists, and I want them all back. It's absolutely ridiculous that somebody can even accidentally do this in Apple Music. I will genuinely go back to Spotify if I can't get all my songs back, I'm livid.
