I recently graduated from college, and almost everyone I've met here has changed his or her major at least once. Most people don't have any clue what they want to do when they are 18...and even if you commit to a career path, if you decide you don't like it you can always go back to school and get a different job. My mom has a friend who has had 3 careers!

My advice would be to go to college and take a bunch of general courses to explore your interests. A college degree is a way to get your foot in the door with many professions, even if what you studied has nothing to do with your job (a friend of a friend was a biology major, now works for an auto insurance company)! College can be expensive, but there are ways to make it affordable. You could always start out at a community college, where the cost is typically lower. If you are worried that your illness will make college hard, my personal experience was that high school was much more stressful than college. Also, most colleges offer services for students with disabilities. You might even be able to get a scholarship for your experiences with your illness.
