Is that what happened?
I've been in your place before, wanting to talk on /co/ about your desire to become just like a certain cartoon character.
It's nice to know I'm not the only one to have done this, and that it's okay. I felt really weird when I did it.
It's okay to want to be Creepy Susie. Figuring out what that means to you, how to get the look and attitude just right, and integrating that into your life, will probably be a gradual and ongoing process.
One thing that really helped me was to research the sorts of trends and people that influenced the character I was attached to. For example you could research French bohemians, nihilism, the goth subculture.
