Anyone Else Feeling Burned Out?

Hello everyone, I have been feeling really overwhelmed with exams lately because no matter how much I study, I still worry that I am not prepared enough. Last night I was talking to a friend after finishing another practice test, and out of pure frustration I blurted out, “take my exam for me” because I was mentally exhausted and stressed. We both laughed since it was obvious I was only venting, but it made me realize how much pressure I have been putting on myself. Has anyone else felt this overwhelmed before a big exam?
