Am I emo or a poser?..... I need to know really badly!?

OK, my personality changed dramatically over the years, and sometimes I ask myself if I am emo. First of all, I am anti-social, I'm pretty much by myself the whole time, so I exclude myself from most activities. I don't actually dress like other emos, such as eyeliner, black nail polish and razor-cut hair, but I wish I did though. I have a huge habit of pulling out my MP3, and I listen to rock music. Sometimes, I even listen to songs about , but it's not a bother to me. I call myself an epic fail because I'm a klutz at most simple tasks, and sometimes it makes me want to cry. I have made many attempts to cut myself but I backed away, and one time I did, but I completely stopped. I spend a lot of time drawing anime, and I draw them based on how I feel. Well, that's pretty much all the description.
