I have been looking into unschooling....?

Remember, there is no form of education that won't leave holes, because no one has the time or ability to learn everything. To unschool successfully at your age, you need to have a plan. You need to know what your graduation requirements are, and find ways to fill that with subjects you want to study, subjects your parents want you to study, and any pre-requisites your might need to get into college. You will be surprised how much you will learn once you have a schedule you like :) Unschooling doesn't mean you can't use curriculum. If you want to continue with maths, you might prefer to use a textbook, or perhaps the Life of Fred books. You might feel more comfortable with essay writing if you follow a curriculum. You might decide that joining the SCA is the best way to cover PE and learn handicrafts, if that's important to you. If you are dedicated, it's unlikely you'll leave out anything important in what you choose to study. Firstly, you'll be interested and motivated enough, and secondly, you'll be reviewing your progress to see if you are happy with your plan or need to amend it.
