Seeing at least one of the comments in response to an article about the recovery of her body, it's easy to see why she killed herself. In addition to the daily pain she experienced from her medical conditions, she put up with bullying and harassment. Some even taunted her to kill herself.
Now she is no longer in physical pain (or so I assume). However, as the comments indicate, she is still being tormented by haters.
What ever happened to respect for the dead?
