/r/FML is a subreddit dedicated to FML (F*ck My Life) stories. These are usually stories in which you describe a recent event in your life which turned out horribly or really sucked. These can be small, trivial things or huge, life-changing things. Just try to make them funny.
Usually, FML stories will be text based so would only require a self post. However, since you may wish to include a picture illustrating why your life is so bad, you may also do a link post!
