What should I major in?

I always taught I'll pursue a degree in International Studies, I like history and everything that has to do with traveling and learning about other cultures, but, I been having second thoughts, mainly because I feel I don't fit with the abilities needed for that career such as debating and stuff that requires to speak up, which I'm badly at. As a second options, I had in mind to major in something like Philosophy, English, Literature, as I like to read a lot, but my I'm not sure I can get a good job or I think that there is not a lot of job offers for those careers, and I don't want to end up being a teacher, which I'm pretty sure I won't be able to do as it requires speaking to a large crowd. My third option was to become a chemist or biologist, because are subjects that I always liked and that I have the ability to work with, but I think that involves a lot of math, which I'm also not good at and that I hate it as well. I should probably mention that I'm good memorizing rather than rationing. Help me please I don't know what to do? :S
