Hi, I used to cut and give into urges time and time again I struggled with arguing my point to others when I said it was an addiction (ya know not everyone thinks it is) but the truth is as you said it is an addiction and it is a habit that is hard to break. What helped me stop was realizing that I was doing nothing but damage to myself and not helping at all just a mere second while I was doing the actual cutting but right after I did it I would cry and just want to do it more and I think it is that way for everyone. Just try and refrain from doing it...It is also a matter of changing your thoughts around IF YOU CAN I know it is not possible all the time but think of something good or just do something to distract you try not to look at cutting as an option at all because it does not help take your pain away.
Stay strong I hope I said nothing offensive.
