When I think about my cycle of Addiction, i see it stretching back farther than my substance use alone. I was addicted to masturbating when I was little. I was addicted to hurting myself and ciggarettes, and then I stopped cutting. But thats because I had started finding substances, anything I could try, and it phased out the old addictions (along with a new mind-set).
I currently have not overcome the problems that make me rely on addictions, but I am learning to live with them. To actually end the cycle of addiction completely seems impossible to me; if I ever think Im 'quitting something' its either because I already have something new or Im off trying to find it. Unconciously, of course.
So congrads to you, for your breaking of the cycle. Mine is very much unbroken, so far. For better or worse, I suppose.
