You've mentioned several times about not wanting to waste your "creative" side. How many art classes have you taken? What other "creative" activities interest you? How has your creative talent been nurtured?
No matter what career path you take, even if it does not flex your creative muscles, you always can have hobbies to satisfy your creativity. Getting a job, or living off your own creativity is difficult. To compete with other successful artist, no matter what field, you pretty much have to be the best of the best to make a decent living. As others have said, you need to learn as much about business, marketing, and accounting as you can. Trust me.
Even if you go the graphic design route, you will be faced with a rude awakening, that through the beginning years of your career, you won't be flexing your creativity. You will be doing grunt work, and the stuff others tell you to do. Again, until you prove yourself to be top of the class, you will be a lacky, like any other job.
I am not trying to disuade you from following your dream. I want you to think realistically. How talented are you? Who are you using as a gauge?
If you think you have the right stuff, go for it. Just remember it will take time before you really come into your own, and can really reap the rewards.
My parents didn't want me to major in Jewelery/Metals. They feared I would never make a living. Honestly, neither of us knew what the work field was like. They supported me though. 23 years ago I started my first bench jewelers job (lacky). I made $5 an hour. My second job, $5.50/hr. Third job $8.50/hr. Fourth job $11/hr. I hated what I did. It was mostly jewelery repair, and nothing creative. But over the years my practical skills grew, and my education proved beneficial. I was better than nearly all the benchworkers around. I had applicable traditional skills these other people didn't have. Word got around, that jobs other jewelers wouldn't touch, I could do. I became a commodity. Sooo... 21 years after leaving school, I finally started my own business. I finally am making a very comfortable living. I finally love what I do again, and am still getting better with every job I do. You never stop learning.
What's missing from my education is real business skills, and everything associated with it. Granted, I know the basic business concepts, and can figure out what I need to do. The business side isn't hard, but it can be frustrating. There is more to it than I thought. So, my advice to you is really to at least get some business understanding under your belt WHILE you focus on photography.
I also highly reccomend studying art. While so many people will tell you that you can learn photography on your own, they do not mention studying art. Doing so will put yourself head and shoulders above all the other facebook photographers that have other jobs, bought a camera and decided to start a business, because photography is easy, and they have been overcome by the "passions".
Good luck to you whatever path you take. But dont EVER think that if you end up with a boring desk job, that you can't still create. Jobs support hobbies. Hobbies bring happiness to your life. Sometimes your hobby can become your job.
