You are too young to think like that. It’s no reason to become sad and you should talk to your parents without any hesitation. They love you and care you. Tell them that you feel sorry on your performance. But do something to make them happy. And the only thing you can do very well is to help your family members in chores and just concentrate on your studies. And scholarship is given only to those who are better in studies. So don’t worry and keep these plans for the future.
