How do I become an Occupational Therapist?

After I complete this spring semester, I will be a Junior in College. I am graduating from our community college just with a general studies degree, and I will be going to a 4 year University beginning in the Fall. I think I have definetly decided that I want to be an Occupational Therapist, but how do I do it? I know I should just talk to a counselor, but I am just curious right now, when a counselor is not available to me. Do I need to major in something specific? Or is there an actual Occupational Therapist major? Any helpful information would be greatly appreciated! Thank you in advance!
