I've always had a theory that the worse thing that can happen to a person is to get their heart's desire.
I've seen people obsess over things for years - possessions, people, jobs, houses - to the point where they think "if only...then I will be happy, finally".
9 times out of 10 when they finally succeed they fall into a depression, because it didn't change their lives into the miracle they had emotionally invested it with all that time.
I can imagine it's a lot worse when that obsession includes body mutilation and your general sense of self. I'm just surprised it's not more common. I bet it is, and they just refuse to acknowledge they are still unhappy, because that would destroy them.
I agree 100%
