I agree with Ladybug--7-3-12 ... there should be no need to disable your acccount, and I personally would hate to see you make it more difficult to re-join the group. You can always remove the bookmark for the site, or move it to a different folder where it isn't seen so readily, but keep it as a reminder that you really DO want to quit this awful addiction. Maybe just not today.
The best case scenario in my opinion is for you to continue visiting until you feel ready to participate again, without disabling or deleting anything. We're here when you want encouragement or support, to help in any way we can.
Quitting is difficult, and it doesn't get easier tomorrow, or next week, or next birthday or when the current crisis is over. But sometimes, yeah, we need to regroup and recommit to get another running start at the forever quit that is within our power to accomplish.
