Do u think im emo?

okay... sometimes i get lonely or sad. sometimes i even cry at school. at my house i usually lock my self up and cry for hours while listening to emotional music. ive cut a couple of times and get really emotional and have depressing thoughts. i get from feeling ecstatic to feeling completely miserable and alone. i like the color black and other dark things but when you see me i dont look emo at all... does this mean im emo?!? help?!?
