Is it important to look into the causes or deal with the behavior itself.
It's a Halacha in hilchos Teshuva that you have to figure out what brought you to failing, and to avoid it in the future. This includes all kinds of things. Like: not being careful where you go/not having a good filter on your computer, being depressed, anxious or unfulfilled, not learning enough Torah and musser, being bored, being alone in your battle and the list goes on and on.
But the power of addiction is very strong by itself -much stronger than all the other factors. So once one is addicted, the main focus has to be on breaking the addiction cycle. Of-course, you can deal with other factors at the same time (a lot of them
must be dealt with at the same time in order to succeed) but you have to make sure that it's not distracting you from your main focus -breaking the addiction cycle.
I know different methods of psychology revolve around this question.
Is there really any room for argument here?
I wonder if you are really referring to the question of
how to deal with emotional issues.
One thing is for sure:
You are most definitely heading in the direction of tremendous success. I'm very very impressed and inspired by you. You are fighting the y'h with chochma and determination and a very powerful strategy. Your
mehalech is the antithesis of the half-measure way - which so often leads to failure and frustration. Hashem should give you tons of hatzlochoh!!!
CHAZAK VE'EMATZ!!!
