From the sounds of it though, this isn't the same as when you usually cut. From how you describe it, you cut just because you missed the feeling of it, kind of like a withdrawal I suppose. You might also have cut just for something to do. You know how some ppl eat to fill an emotional need such as boredom etc? Maybe you decided to cut to pass some time, and since you could do it and you missed the action of doing it, you did.
