If you have never been through it you can't understand it. Its as simple as that. You can't understand why someone might drag that blade across their arm, punch themselves till their bruised or whatever they might do. That's another thing, self harm isn't just cutting, its so many other things that people don't even realise; scratching yourself, pulling out your hair, taking scalding hot baths, things like that, if done purposely to hurt yourself are all self harm too. People who self harm shouldn't be judged or classified as emo and the people who do it for attention are ridiculous. Self harm is some peoples way to cope, who is anyone to judge their coping mechanism? Most self harmers hide it as much as they can and they need help, not people calling them attention seeking, and its not taken seriously enough as an addiction.
