Congratulations, I'd suggest taking on the mantle of quat as opposed to quitting, ie give your self permission to assume 100% confidence in your ability to be done , for good.
Learn AVRT, reread RR:TNC and all the threads , great guides in learning how to live comfortably with residual desire.
Being ashamed of what we have done in the past is one thing, attributing that shame to our current selves ( the 'myself' as it exists this second and all future seconds) is at the very least counterproductive . "Myself" Now includes the self that Quit and ongoing shame only serves the AV .
