My sponsor told me a simple rule: You choose a sponsor because you find a person who has some things that you want.
Very simple.
My sponsor was a person who was very different than I. For one thing, he is not a Yid. And he acted out much more dramatic ways than I did. There were other differences, too.
But he was a sexaholic who really understood how insanely and absolutely essential my porn and my sexual escapades felt to me in my sickness, and understood in a humble way what it really is to be an addict.
No religious non-addicts I knew could do any better that show sincere, bleeding heart sympathy for me - but they all were people who saw themselves as standing above me, looking down at this pathetic man, and hoped to 'pull me out' somehow. They loved me and were truly sincere - but sincerity is not nearly enough...at least for me and for any of the other addicts I knew who were pathetic failures at living sober.
My sponsor was completely different. Here was a man who was sober for a few years, yet never once looked down on me. He could show me how stupid i was and how messed up my thinking was - yet not once did I ever get the impression that he felt any better than I! He knew that he did not deserve the credit for his sobriety and not himself. he was a loser at sobriety and a loser at acting out his lust - he could do neither. Boruch Hashem, Hashem granted him sobriety one day at a time. What credit is there to take for that? There is no madreiga in what you are given through a pure Chessed. Even if you have the wisdom and desperation to take hold of that Chessed with both hands - it was still a Chessed, and still is.
Here was a person who was well-adjusted to life, a job, a wife, and to his Higher Power. I had none of those.
Though I was frum, teaching mishnayos to ba'alei teshuvah, keeping Shabbos and loving learning, I was certainly not well-adjusted to my Higher Power! I had many problems with Him and felt certain that He had even more problems with me. The tip of that iceberg was that I was still absolutely convinced that sexually acting out was in my very best interest - that was why I felt I needed it so badly, wasn't it? Of course it was. I was truly screwed up.
I related poorly to my wife, because I had accumulated so many secrets from her that in my disease I have a double life, and my wide is the oblivious evyon at the door picking up the scraps of me I throw to her - the man she married to be her companion in this life. I kept so much truth from her because it would hurt her so much. The guilt is not my issue here, at all - my point is that I just couldn't shtim.
I related poorly to my job, in that I was abusing the computer at my work, came late to work because I slept late routinely to act out, and because in my gut, I resented the 'establishment' for setting limits on my pleasure by looking over my shoulder and suspecting me of being a deviant of some sort...heh-heh :-[
I chose a sponsor who had all my sickness - and yet had all the things I looked up to but knew in my heart I'd never ever be able to really have. To fake it - yes....but to really have? How could it be? I 'knew' that when I died they'd be maspid a different guy than the one on the box - the real me was such a deep, dark secret. So I chose a person who had all the things I didn't have, because of my disease.
Now I have no secrets, thanks to stating with my sponsor and having the love of all the other members of SA who are as sick as i am and are growing healthy one day at a time by Hashem's Chessed.
Hatzlocha! hashem will definitely help you every step of the way, and you are making real, painful efforts. Keep it going, brother!
