First, I hope to give it up, I hope to extend my period of abstinence longer and longer. But, at the same time, I'm nervous about that. Can I really go 50, 60, 100 days clean? And I know my plan isn't good, because binging will probably make me want it more. But at the same time, I've tried to stop cold turkey and it hasn't worked. I have an uncontrollable urge, and the fact that I never plan on doing it again makes me want to do it more. Then I feel terrible guilt and I fall again. And it's a cycle that goes on for a few days, usually until Shabbos when I have a spiritual revival, I make a new commitment, only to fall again soon after.
When you ask what am I afraid of? First of all, I enjoy doing and I'm not ready to give it up. But, I think you're right, there is real fear there. The fear is that if I try to genuinely stop, I won't believe myself, as has happened in the past. I will fall and I will have crippling guilt. Stopping halfsies (if I can even do it) will reduce the amount I do it, and will reduce the guilt I feel when I do it.
You asked, what happens if you have an urge on day 15? In the past, I gave in. Because I had an urge. And there was no light at the end of the tunnel. Only fear and guilt. But now, if I get the same urge, I hope I can tell myself, "only 2 weeks... you can do it... and if you wait 2 weeks, you can get the same result without the guilt." My hope is that this can be a successful motivator.
