I read a very similar article on the web last year, I believe it can be part of this behaviour.
Animals will go as far as chewing their limbs off to get out of a trap, or will self-mutilate due to frustration.
With this known, is more of a reason for those who do this to give meds a try, they may help with the brain chemistry that goes with this. Statistics have shown a rapid increase of SI amongst young female teens, almost the way anorexia had a rapid increase a few years ago.
I think this was an interesting topic you posted here, thanks for sharing it with all.
High amounts of stress and prolonged stress really plays havoc on our entire being, physically, mentally, upsets almost the whole body and brain chemistry.
Cortisol levels increase, amongst other hormones when under stress.
Damn, stress.
