hello xBabyGx. we get the need/(craving, almost like) to do this too. T said that it becomes a coping mechanism,......like a way that we deal w/ stress and/or other difficult events in our life. she suggested other ways of coping where i know i'm feeling something but are not harmful such as keeping a rubberband around my wrist and pulling on it when necessary,.. or taking a cold shower.........

hope this helps...............beadlady29
