My whole life has been ruined by my parents.

Stay away from them, they are bad people, believe me, believe in reality, save yourself from being harmed by them, I will be harmed, there is nothing you can do now, I don’t know if your life is really in danger in this home , don't argue with them and don't pay attention to them. Pay special attention to your personal safety. Ask carefully if they will really kill you if you don't do well in the exam. Only when you are sure that they won't do it can you feel at ease. Stay away from them after graduation. Also, be careful not to care about your appearance or the eyes of others. If you really care and want to eliminate the feeling of inferiority, you can go for plastic surgery
