Please avoid doing it.I have carried overwhelming emotional pain since my childhood.The thought of releasing a bit of it through creating a physical pain as a distraction,crossed my mind,but never acted on it.I know my cousin did it( she showed me her scars that were under her clothes,so many of them.).It was scary scene and may be that is why I I didn't. BUT I am constantly looking for ways to reduce my emotional pain,mostly alternate healing techniques and self soothing and positive distractions like art and craft.
