I'll go first:
A crowded cocktail party where I am forced to shout over loud techno music to make small talk with complete strangers while wearing a weird outfit and an uncomfortable pair of shoes. Also there is no where to sit and all they are serving is cooked carrots and sparkling water.
Not that that's what I have to do tonight or anything.
(This picture is the first result when you google image search "personal hell." It's unclear why but it was obvious that I had to use it)
