After hearing Nightmare Moon's perspective of what happened 1,000 years ago, the mane six agree to help her, instead of Celestia.

So Nightmare Luna knows this isn't a trick, she puts up six trials for each pony, each with the same theme: Their worst fear.

Rated T for Tia's behavior in the second Prologue. (nothing really bad. )

Not all chapters are sad, here are the ones to look out for if your feelsy.
Apples to the Corpse
Blind and Homeless

A series of silly oneshots. Twilight steps in a bear trap! Celestia screws up big time! Tank! All this and much much more!

I am so tired right now oh man enjoy!

A great evil has arrived on the Apple farm, and also it has DESTROYED THE APPLES!

Applejack and her sister Skeleton Bloom are about to embark on an adventure that will test the apple powers inside of them! Also Apple Bloom was on fire a lot and also was reduced to bones.

And also if you keep reading you'll get to see a fight on a train and also a battle of wits or something.

A really popular and good looking guy comes into possession of a Pinkie Pie shaped flash drive. The seemingly ordinary device holds within itself a horror like none seen by this world.

Pinkie_Crazy.png was not meant for this world.

Pinkie_Crazy.png is coming for John Ponyfan.

(This may be the stupidest thing I've written. Enjoy!)

Ever had a bad day?

Ever been on fire? No? Well Twilight has. It was a bad day. Ever choked to death while your friends watched? Ever accidentally kill your best friend? Ever step in your best friends remains and die because your foot got stuck?

This is the story of 12 ponies and a Spike. This is the story of their really really bad day.

A great evil is being awakened by an old friend.

A mare comes into possession of a box that could save the world.

Two old friends have lost all that they love, and are willing to kill each other to make things right!

The fate of Equestria hangs in the balance!

(My attempt at the worst written fic i could think of)

Twilight has been alone for a long time. She's not sure how long anymore, but the color of the sun is giving her some ideas.

Twilight stopped dreaming a long time ago, but she is now plagued by visions. Visions of the past. Visions of the worst moments of her life.

Twilight is feeling really annoyed right now.

Partially inspired by It's Such a Beautiful Day by Don Hertzfeldt, if only because it put me in the mental state to write this.

After being sucked into the magical land of Equestria, YOU find yourself as the legendary Brony Hero in this exciting interactive adventure. Will you find the Time Orb and restore peace to the land? Or will you marry Fluttershy? Will you defeat the evil demon king Tirek? Or will you marry Luna?

With 21 endings to choose from, only you can decide your fate!

This is a fic based on the Time Loop Files, the format of which was first codified by Innortal on fanfiction.net.
Here's a brief guide.
The basic idea is, one character (the Anchor, usually the main character of a fictional setting) is looping back to the very first moments of their parent series every time either they die or some kind of time limit expires. They of course end up monumentally stir crazy given enough time.
Eventually others start to loop as well.
The reset is not always perfect. Sometimes a loop's history will be different to the "prime" loop, or canonical plot.
"Crossover" or "Fusion" loops also occur, randomly. These can involve the home loopers having a guest, or the anchor for one universe spending time in another, or replacements of one character by another.
Vacation Loops are where the Anchor (or others) decide/s "buck it" and lets off steam by doing whatever comes to mind. There's little or no attempt to maintain the original timeline.

In addition, and particularly more recently, it should be known that this story has a collaborative element to it - people may submit loop ideas or loops, ideally at the Spacebattles thread (a link to the current version of which is on the Trope page), and they may become included.

There's two page image options, thanks to Filraen - the current page image has been edited by the original creator from this work of theirs.. The other one is here:
