At the risk of exposing myself... I am a recovered "hitter" also. In order to recover from this I had to take a serious look at when, how, and why I was doing it, what I was feeling, how I was internalizing, and why this was a solution for me. In my case, I think that underlying self esteem issues, paired tendencies that leaned towards being a perfectionist, made it VERY difficult for me to tolerate the influx of other people's critisism, especially if it was in a situation where I was geing yelled at or treated in a way where I internalized it as I was being told I was "bad" "worthless" etc. For me, I hit myself for reasons that were twofold: 1) because I could control it. You see, if I took over your punishment by hitting myself while you were disciplining me, I then become my own discipliner. I can control not only how long the punishment lasts, but also in some strange way it allows me to control what the punishment means to, and about, me. I am beating my message into your head, not mine. Also, 2) self hitting was a way by which I communicated back to you that "I got it." It was as if I was saying "See! I get it! Yes, I am worthless!!! I can take it from here!!! Please leave me alone!!!" Finally, self hitting was effective for me, because it would cause the punishment, discipline, and critisism that I had such a hard time dealing with, to stop... so, long story short, it was a coping mechanism for me for many years. The question as to whether the way my discipliner disciplined me was too extreme or unexceptable, vs. whether I was just for whatever reason unable to tolerate "normal" parental discipline, is irrelevant. The fact was that it was what it was. As you are "live" in the situation now, where as I am speaking as an adult, looking back on it in my youth, I would advise you to seek family counseling, so that you can at least have a trained professional witness and make recommendations about what dynamics are contributing to your situation and what you can do to help it to come to a stop. I do not have any learning or neurological or phsyciatric disorders. Maybe for me it was just the perfect storm of a low self esteem in childhood, mixed with perfectionist tendancies, mixed with a single-parent mother with 4 kids under the age of 6, who worked full time and was completely stressed out and yelled a lot. Like I said, irrelevant in terms of blame. I just encourage you to try to learn more about it. :-)
