This describes how I was as a teen. I didn't know of the term until now. I am no longer this person. I am a highly spiritual being now, very connected to everything and empathic and gifted.
In hindsight, I don't know what caused the flux of depressed teens during that time, other than a change in human emotional evolution, but based on my experiences, "emos" are unaware empaths. They do/did not know that they are special, spiritual beings, and/or may deny their true selves, likely because there wasn't much support for the emphatically gifted back then. It's hard to be a minority. It's easier to embrace oneself when there is a basis of understanding, social, environmental, and societal support, especially family support.
Sometimes it's a matter of sink or swim, of learning through experience, and having compassion for what we don't (yet) understand
We can be anything we want to be. Life is what we make of it. We can create further separation, or we can try to understand our "enemy". Only through love is there growth. Everything else is not conductive to a positive world or a positive existence.
Peace and love~
