Hi A.:
I have been a teacher for over 20 years. I also have two sons. My oldest is a lot like you. Bright and hardworking and a very good student.
So, now that you have a sense of who I am I want to tell you that you will be okay. Your parents might be upset, but eventually, they will be okay too. I am sorry that you think or know that you will be in massive trouble for one bad grade on a math test. That seems a bit harsh and unfair.
You do not say how old you are or what grade you are in, but I am guessing a freshman? Please know that there is a big world out there and not one single person in it is perfect. Not the greatest doctors or inventors or professors. Not the world leaders, ballet dancers or humanitarians. To be perfect is to be not human. The beauty of being human is in the great variety of perspectives and experiences and many of those experiences only come to us after we have failed at something. Even if your parents cannot see this, I want you to see this. I hope that you will try to embrace the idea of accepting, even embracing, a failure, as I know as a teacher that this truly is how we learn. And, BTW, a perfect GPA and a degree from the "perfect" college does not guarantee a perfect, happy life. Parents do want the best for their kids, and sometimes that means they think they have to makes sure that their kid is on track for a perfect life, but as I have said, no such thing exists.
As for telling your parents. Be honest and explain what happened. Having a nervous breakdown means that you need support and perhaps some counseling to help you deal with the stress that you are clearly experiencing. I am sure your parents do not want you to suffer such extreme distress. Be honest with them and ask for help. Please be sure to post what happens, because I will be thinking of you.
