Sorry to hear about a tough day in Denmark Momo. Perhaps the time has come to visit Japan instead?
I fully agree with Battleworn. Go through the handbooks again and again, in fact, get a chavrusa / partner for it and study them with Rashi! There really is so much depth in them.
As for Duvid Chaim's group, I dont see any contradiction between what you aim to achieve, and what you
are accomplishing already.
Learning to see beyond our own selfish needs is the exact response needed to beat the yh of "me". By slowly learning to focus and respond to the needs of others we come to realize that what we do affects others directly as well as indirectly. Yelling at ones wife will affect her day one way, while complimenting her will definitely have a very different effect. She gave you the cold shoulder all day after you yelled? Well, next time you may come to think twice before letting lose because you didn't like the result. She made your favorite supper and joked and laughed all night after the compliment? You are going to want to keep receiving that response, and will be encouraged to compliment again. We react to positive reinforcement.
Eventually, you will
want to make others happy by giving to them, and in return, will find that true happiness is in giving. And by filling yourself with
healthy stimuli, slowly but surely your need to act out will ease up.
Thinking of others and giving, is step one in dealing with the source of your internal emptiness. Acting out is nothing more than a putrid Band-Aid covering a festering wound.
Momo, have patience with yourself, although Im sure you are rolling your eyes as I say this! Remember, the addiction wasnt created in a day. HOw do you expect it to leave as fast? If I cut myself, the act of cutting may have taken mere seconds, but the act of healing will take days or weeks.
Let go, let G-d, and daven!
