You know, I did not even read through all of the replies here. Shit, I didn't even read one, so if this advice sounds redundant, then I am sorry.
Realize that you don't need a college degree to get into computer fields. Study and get your A+, N+, and then go to work for some company and let them finance you to get your MCSE. From there you can branch into a specialized field of study and get your MCDBA, CCNA, OCP, or whatever strikes your fancy. You can get your A+, N+, and MCSE all within one year of minimal studying.
Stay in college and focus on what you like. The Physical, Nutrition, etc.. part of your life. Use the computer certificaitons to support yourself and save money so you can open your own gym, personal training service, chiropractor office or whatever.
