I've seen alot of people label themselves. Labels such as "emo", or "goth", and even... "vampire". It's all extremely ridiculous. You guys need to stop being so easily influenced by media and surroundings and learn to think for yourself. You don't need a label to be important to society. Just do your thing. It's just, alot of people think it's annoying when people go around saying "Dude, I'm so emo" or something stupid like that. Come on, really? And if you subscribe to labels because "your life is so terrible", you take to much for granted. And cutting yourself doesn't make things better, it's absolutely ridiculous. Just be yourself, don't label.
{Note} I guess this started to become a rant on emos too. xD
ONE LAST THING: If you really think you are a vampire, like, for sure, see a doctor.
