re-reading your post there some stuff here thats going to give you problems with a lot experienced members and martial artists here. there are also some porblems i have too with what you say, especially about honour and discipline.
if the 14 year old had been trained with some disciple and honour he wouldn't have started on you and beaten the crap outta you. and you were stupid for rising to a petty insult.
evidently you were also trained pretty poorly in karate and sadly probably in a mcdojo, i'm sorry you had a bad experience with it. I'm glad you've found an art your comfortable in. (oh and its jutsu not j itsu)
Go seek the advise of a qualified instructor.
