How do i move on from a class that i failed?

ok so i failed a class from summer school and i'm so afraid that it might affect me from doing my internship in the united states. i did everything i could to pass and i still didn't. i haven't lost my scholarship in college yet since most of what i have to do is to just work at school. i don't plan on telling my parents since i know i'm not ready and i know they can't handle it. should i retake it as soon as possible? the part that i had a hard time on was the math section and because i'm asian, people expect me to be smart and all in it, but i'm not. the class was like a pre requisite for some other classes. i pass the major classes. it's just some of the general education classes that i suck at, especially when it has something to do with math.
