I'm not sure how things are in the UK for this, but it's becoming a fashion / style over here.

Emo used to be people with real issues, not everyone just wears black everything and acts like their lives are "soo incredibley fucked up" and they're fine. They're just into it for the style and to grab attention. We had people cutting themselves daily just for attention the last 2 years at school, it's ridiculous. RI-FUCKING-DICULOUS
