these are real though, not some movie, so if you have a weak stomach i advise you not viewing these pictures!
edit: I have personally looked through all of them, and afterwards I am glad because I have said "i'm gonna kill myself" out of desperation or frustration, but after looking at these photos and realizing that there is a way out of any situation, and once i had gotten past the hard times, i realized i could never take my own life, or anyone elses, it's just that these pictures are that graphic!!! :(
