I'm afraid i'm not bright enough

Hi I'm 24 and have finally decided to go to university and get my degree. I have been looking at degree choices all my life and have jumped from one to another being indecisive and not being able to decide what I want to study. Saying this civil and structural engineering has always stuck out to me its fascinating and I know its something I would love and enjoy doing it. But the thing is I do not believe that I am bright enough to take this course. I passed math at GCSE with a grade of C although i can say i didn't put 100 percent into it. I badly want to become a engineer but its scares me and having people tell me I'm not gonna be able to handle it puts me off even more I'm now even more confused to whether I should go to uni at all.
