I'm sorry to hear about what you have been through. It's not right for a teacher to say that to you. Your teacher is there to support you. I don't blame you for being angry. I would be annoyed and upset if a teacher said that to me. Maybe your teacher is stressed out because of his job or issues at home. Or maybe he is one of them people who expect people to perfect. Don't listen to his rude comments. I hope you be okay
