http://www.mirror-mirror.org/selfinj.htm"It has been reported that many people who self-injure have a history of sexual or physical abuse, but that is not always the case. Some may come from broken homes, alcoholic homes, have emotionally absent parents, etc."
"Most people who self-injure tend to be perfectionists, are unable to handle intense feelings, are unable to express their emotions verbally, have dislike for themselves and their bodies, and can experience severe mood swings. They may turn to self-injury as a way to express their feelings and emotions, or as a way to punish themselves."
"You may be wondering why someone would intentionally harm themselves. Self-injury can help someone relieve intense feelings such as anger, sadness, loneliness, shame, guilt and emotional pain. Many people who cut themselves, do this in an attempt to try and release all the emotions they are feeling internally. Others may feel so numb, that seeing their own blood when they cut themselves, helps them to feel alive because they usually feel so dead inside. Some people find that dealing with physical pain is easier than dealing with emotional pain. Self-injury is also used as a way to punish oneself. If they were abused, they may feel ashamed, guilty and blame themselves for the abuse, which in turn causes them to feel the need to punish themselves by inflicting pain to their bodies. Some people have such hatred for themselves and their bodies that they will carve demeaning names on their bodies as a way to remind themselves of how terrible they are. Whatever form of self-injury is used, the person is usually left with a peaceful and calm feeling afterwards. Since those feelings are only temporary, the person will probably continue to self-injure until they deal with the underlying issues and finds healthier ways to cope."
