Don't change it. Even if you change your family name, you can't change your blood relationship with your father. You are still his child after all. The divorce of your parents will hurt you. In your heart, you must hate why your father would abandon your mother and children. But divorce is not what parents are willing to choose. They must have their reasons. You should not punish yourself with others' mistakes, Changing your family name will not change the fact. When you grow up and get married, you will understand what they have done. I hope you can open your heart soon!
