I would recommend joining a creative writing community of some kind. I am a member at two different sites and I find great comfort and support from being able to share my writing with other writers, as well as receive help and feedback when needed. Your request is actually a very common one in a writing site so I am sure you would have no trouble finding someone to help you out. If you do not know of any writing sites, a simple google search for "creative writing community" will lead you in the right direction. Good luck with your piece!
You should major in English first of all, because you want good spelling, grammar and a wide vocabulary. Do not take Creative Writing. If you do it could result in you not even becoming a creative writer. It would make you lean more to being a creative writing teacher.
