your Rabonim are מלאכים. You are blessed to have such compassionate and understanding great souls supporting you. From this you learn that you have value, that they see the neshama crying to be close to his Father, to be bitul in His Ohr.
This is who you are. You are not the you that you become when you are possessed. You know you are possessed at the moment when you stand outside yourself for an instant while you are buried deep into the porn (and mast?) and see yourself, and feel, "feh! What is this I'm doing?", but you turn away from that insight and give yourself back over to the pleasure. This is our moment of truth. But seeing the bechirah right in front of our minds, as we stand outside ourselves for that moment, for us addicts it not enough for us to stop. We are truly possessed. And we are powerless to stop. On our own.
Be gentle. That's the only nechamah you have right now for the pain of how far you feel from His shelter. But he has sent you these melachim. He's sent you to GYE, a Holy place, filled with understanding and oneg and simcha and chizuk.
But melachim can't make choices for us. And when we are possessed, we are beyond making choices. So we have to be pre-emptive in dealing with the yh. We have to put filters on ALL computers, and electronic devices that have access to the web. We need to continue to be involved with other people on the same path--groups, 12-step or otherwise, etc. The handbooks are filled with the "How to's". But at the end of the day we're left with the bechira. Not to choose to stop. Because we can't. But to choose to do what we can realistically try to do and to ask Him to help us do that little bit. It may be tiny baby steps at first. To make it through one whole day might seem like a huge project. But soon you'll make it for one day. Then comes tomorrow. And one day at a time you become yourself again.
And in this there are no half measures. You're either in or you're out. Then, no fall can take you off the derech. You'll keep at it and keep at it, and you'll get closer and closer to Hashem, and pretty soon you'll just ask Him to run the show because you're just too exhausted and useless and impotent to battle the yh. And it will get less rugged, though my experience is that it still keeps cropping up in ever more sophisticated and sadistic ways. Today I was walking my dog on a trail in the woods, in pain, and nauseated and depressed. And suddenly I'm having a fantasy. It never ends. But it's a journey so worth the taking that your dreams of being a truly tiereh Yid will all come true. That's a promise.
