KJ - no that is classified as a really creative coping skill.
I also started dissociating and switching...at three. Prior to that i had attachment disorders with both parents.
Acting out started around 4 and mom was taught to pin me to a wall until i told her she was the boss... I started repeating the abuse that was happing to myself at age 6 and depression hit by 7 which was when i started realizing i had the power to kill myself if (rather when) i wanted and though about it daily from then to now. Different forms of self injury started around 9 which didn't turn into cutting until 28.
