I think the motivation behind it counts and also how far you take it. Once something becomes a hinderance to your life it has definately gone too far. I was once a cutter for depression reasons, but now looking back it wasn't about destroying myself it was a cry for help. It was the pain i was having inside finally coming to veiw on the surface so that someone might see it and help me. I was also just numb and wanted to feel something and pain worked mroe than anythign else. there might be some that would say it was self destruction, but I viewed it as more a life line, because really at that point in my life I just wanted to fade away.

The cutting was a very small managable thing, but once it starts to grow to a point where you are doing large amounts of harm to yourself is really when it becomes destruction. I think it happens more with addictions to things that masocism.
