Is it normal to fear this is all for nothing?

Since middle school, everything ive done is so that i can get into a good college. I work my butt of at school and take all honors courses, but i fear that this will all be for nothing and I won't get that dream job or dream college. If I die tomorrow I will have done nothing but prepare for something that never came. I want to do something with my life, and even though ive won awards and done volunteer work I still feel like ive done nothing
