What are some good career options for me personally?

I'm in Grade 11 currently, and I still have no idea what I want to do after highschool. I'm intelligent and I try hard, but I'm also very shy/antisocial. I was planning on being a pastry chef, but I don't have a lot of patience at all and I just have a bad feeling about going to college for that. I have a 97% in my media studies cl right now and I find it very interesting, but again, I find it very difficult to socialize. I'm good with writing, but I think that I'd get bored writing for a newspaper or being a journalist. I'm also interested in psychology and child development, but I always feel awkward around children and don't really know how to be a leader. I like direction and I'd prefer a job where there isn't a ton of stress and deadlines. I was thinking about being some type of secratary, but that's not much of a career. I'm really good with computers, I have organizational skills, I take instruction well, and I am pretty intelligent. I'm more of a written learner than visual or hands on. We had to choose our courses for grade 12 already, and we can change them before it's too late (when grade 12 starts). So, I was wondering what kind of career choices would interest me of your opinions? Even if you sound somewhat like me, what career do you have or are you going to college for? I took gym, 4 anthropology psychology & sociology courses, and a food and nutrition course, but if I'm changing my future plans for what college I should go to I need to choose the right courses so I fit the prerequisites. Please help!
