Is there no academic probation at your school? How do they let you fail so many courses and still be there? Also, I’m sure that if you tell your parents “I hate what I’m studying and failing most of my classes. I need a year to work and think about what I’m going to do so that I can pursue it fully and stop wasting my / your money,” that is a reasonable and mature thing to request. Let go of your assumptions about what they will say. It’s worth negotiating with them.
I second onceuponamom about seeing a counselor. When I had an episode of depression last semester, I didn’t want to go to any of my classes, even the ones I initially loved. A symptom of depression is anhedonia, the inability to experience pleasure in normally pleasurable acts. Also, utilize any free tutoring services on-campus / professors’ office hours… Don’t LET yourself get to the point of failing.
Does your college have a liberal arts degree? That might be something to consider. Secondly, how do you pick your classes each semester. It might be tough with the short amount of time left, but it will really benefit you to take a variety of classes each semester. Maybe a smaller amount of business will be more manageable.
As for jobs that can “change the world,” let’s see… Education? Probs not. Nursing? Public health? Law enforcement? I think you would really like journalism or working for some magazine; combines art, maybe business, computers, writing, has the potential for a lot of variety.
What subjects do you do well in / don’t hate / are closest to getting a degree in? Just take the minimum courseload allowed, focus on doing well in those classes, and when you feel confident about that, look into doing some networking / getting informational interviews with different professionals in the fields you are interested in to figure out what you want in life. That’s a project that should keep things interesting for you. I’ve had the same struggles with being bored by some of my classes, but at the end of the day, it’s a means to an end.
