Should I do marching band or color guard?

I cannot decide on which one to do! I go to this middle school where it is 7th through 9th. I am doing colorguard right now in my middle school band And I am a 9th grader. I am having a hard time marching and doing colorguard at the same time and everytime I look at the kids that are marching I wish I were in their shoes. Don't get me wrong, I have fun I just can't really march, twirl a flag, and spin in a circle at the same time. And we have a HUGE performance in a week and our colorguard teachers keep on changing the begining of our routine! I'm crazy stressed out about it so I am leaning toward marching band when I go into high school in 10th grade. I play the clarinet. Tell me which one I should choose and why. Thanks!
