Constantly banging your head will eventually cause a bleed in your brain (and possibly a fractured skull).....a brain bleed is also what people get when they are having a stroke, and you know what damage strokes can do....while its nothing that outwardly you can feel at this moment, you keep doing it, and it wont take much longer for your brain to hemmorrage, which then leads to alot of other complications that you really want no part of.....brain swelling, brain stents, coma, death....not pretty....if you feel you must have an outlet somewhere, find another method.....sorry for the bossiness of my post, but what you are doing is very serious and has very serious complications and of course we all want you well and healthy!
