Future seems uncertain

I'm a regular high school or I guess a incoming freshman student and thats the problem, I am good at school and an honor student but the future still scares me. I feel stupid because I probably am, I know I just got lucky but since people call me smart I feel like I need to live up to it but my lazy ahh just can't. Now I'm about to go into college, I know what I want to do but I just can't find the drive to do anything and I'm starting to be scared about my future, I don't know what to do and I always feel so stuck and unable to move so friends, the future just feels so dark and scary.
