Why are emo's so depressed?

Classifying "emos" as being depressed is a stupid and stereotypical, being an "emo" is a reflection of the music you listen to and your sence of style.. people like to make a relationship between being depressed and being an emo, because of the generally sad and suicidal lyrics related in certain emo songs. Depression is a serious disorder and should not be classifyed with being an "emo", as you may know not all "emos"are depressed, and not all people who are depressed are "emos".
