I need life advice........

I'm studying management ( finance and accounting). This year I haven't been able to study properly. I've been under a lot of psychological pressure since passing my baccalaureate exams. I wanted to take a year off, but I haven't. Since the beginning of the year, I've felt extremely exhausted.But despite that, I continued and studied. However, I didn't attend the second semester and stayed home... Tomorrow the exams start, and I haven't studied for even a minute. I don't understand anything in the material. My question is, should I go tomorrow and take the exam? I'm sure I won't pass, and they'll take me to the " session de rattrapage), and I'll have more time to study. Or I could stop studying and return next year.
