Am I really worshipping the devil by being emo?

The other day I was talking to an old friend I haven't seen in months and when I told her that I'm a emo girl she told her mom, she got mad and she said I worshipping the devil by being emo, listening to emo music and even painting my nails black! And after I heard that I was very concerned and scared. I'm not really doing anything wrong, I don't practice occult practices, I don't cut myself and the music I listen to doesn't affect me in a negative way. So please tell me: If I'm emo does that mean I'm a devil worshipper? Am I really being lukewarm? (Revelation 3:16) I do believe in Jesus as my Lord and Savior but now I'm beginning to think I'm going to hell for being emo. And please be serious about this question. I don't want to be thought of as crazy.
