being afraid, thinking about going through this and not relapsing ever again.. wanting to help others? all that is a sign that you are into this.
obsession for me is just trying to focus on doing things right while rebooting, trying to remember each day that i am recovering porn addict. everything is a little bit different, watching movies, using internet, listening to music, hanging out, topics you discuss, words you are using, thinking patterns.. you do everything a little bit different when you are rebooting. at least you should try, thats my point.
EDIT: you mentioned stopping PMO, waiting and carrying on. i guess waiting is your word. most of us miss that part, we just carry on and if our brain is really like that of a heroin addict, imagine the task at hand without focusing on that crucial part of recovery
