Either I can't identify it or the word is simply missing from the English vocabulary, but I understand the feeling you mean. I consider myself a writer, even though I haven't felt well enough to do so much in the last few years. Even if people hear this, they say, "Well, you're an artist! You should put your stress and troubles into your work!" Yeah, let me just get on that, it's so easy.

I have also run into the same things as you with people calling me the "author", "writer" or things like "English freak" (not in a bad way). Everyone tells me to write a book, like it should be easy because I like to write. Sure, I could write a book in a day, but it would be crap, at least to me. Even on birthday cards I get a hard time! "You're a writer - that's all you put?" for group cards and stuff. I get hassled about not speaking concisely, and am told that because I write, my thoughts should be lucid or something. Just because words are involved, that doesn't mean speaking relates to writing at all. In fact, I've found quite the opposite in people, most of the time.

Top it off, if I tell someone my college focus or that I like to write, I automatically get pinned as some kind of liberal journalist slacker or Emily Dickinson-like shady poet. My appearance also matches the stereotypical view, though obviously there isn't one as defined as a rocker like you describe.

I feel ya! Just stay true to yourself. That above all things. I just mouth off when someone gives me slack or says something stupid now, but I don't know if I should necessarily recommend that. XD It feels good though...
