Teen Gothic

Long story short I am a closeted goth. I listen to the music for years and desperately want to dress goth, but the issue is my parents. Mainly, my dad. I am an adult but based on the way he has reacted to previous discussions of this nature I am still anxious. The fact that he is a diagnosed narcissist doesn’t help either . I am sure he will say it is creepy and weird. My mom was an OG “alternative” so I’m not too worried about her. Is there a way that I can present this in a way that he will understand?
