Fic finding

so hi everyone, this is my first blog post so I'm sorry if don't get the format right. I am hoping someone here will remember anything about this story I've been hoping to find for nostalgic reasons and because I am bored as of late. It's a story I listened to on youtube back in the 7th grade and I'm guessing has since been removed since can't find it anywhere. Here is a "summary" the details are fuzzy since it's been a while, spoilers ahead. Twilight and Celestia are leading a charge for some war I don't remember why, Twilight is knocked into a coma and wakes up sometime later (i'm about 90% sure she's missing her horn but don't quote me on that) gets a letter and sets off to find her friends with Spike. Now i don't remember the specific timeline of events so i'll just list what happened to Twilight's friends, Rainbow dash can no longer fly, probably some accident i think in canterlot, Applejack is...depressed i guess don't know about that one, Rarity and Fluttershy find Twilight and Spike. Twilight and Spike are in a carriage alone with Fluttershy and she isn't talking, it's later found out she's mute due to her tounge being cut out i belive. Rarity makes animal clothing (not clothes for animals) and Pinkie went insane and is hold out in the castle of the two sisters and dies somehow.

Any help in finding this Fan fiction will be greatly appreciated. Thank you!
