I hope whatever you choose to do turns out well for you.
This isn't the exact same thing, but my parents did not like me painting my nails black. And although it wasn't a "goth" thing with me, I just really like the way they look...it was a shutdown of self expression that I think all children/teenagers need to go through as they develop their identity. I could see how having your music shut down be a significant issue for you, as a person's musical choices often correlates, in my opinion, to their identity as well. HUGS to you! Kit
