I Am Under A Lot Of Psychological Stress

Hello, I am a 20-year-old woman, I have been driving for a year and a half and my nerves have been ruined. To clarify, this is because I started it in Bulgaria, but later I went to study abroad and it was assumed that by the end of last summer I should have taken it, but I was torn on the practical. Now, a year before the leaflets expired and I had to reappear, I quit my job and university and went home to try again. They didn't come correctly from the company, I wanted to have the opportunity to try at least 2 times before the expiration date from the leaflets and I warned them long before I went home, and in the end it turned out that they reserved an exam date just before the end of the year. However, different situations experiencing, it's all largely a matter of luck. My biggest problem has to do with my instructor's behavior. I know I can't do it, I make mistakes, but overall I'm doing well most of the time now. However, the moment I get confused or hesitate about something, he starts shouting at me "Come on, come on, come on, horror ... what are you doing ..." etc. and when I try to explain the reason to him for the mistake and to ask him a question, he interrupts me with the words "Shut up, only the guilty are explained." I am more tender and vulnerable, I am kind to everyone and I expect good treatment in return, yet I do not pay so much money to be beaten. I know that the person is probably tired, he works under a lot of stress, he may have personal problems, but I threw everything away to get home earlier to pass my exam, I sacrificed a lot, from here I try to do most of my homework, I have to stay in the hospital, but I use every opportunity to take a class and improve my skills. He keeps his distance, I think he likes his other students more than me, for a reason unknown to me. The moment he starts yelling at me, I get distracted, all desire passes and I have no confidence that I will succeed in the exam. Please give me advice on how to deal with this person and how his psychological attacks do not affect my self-esteem and my confidence that I will succeed. Thanks! I have any desire and I have no confidence that I will succeed in the exam.
