Someone help me, with my past mistakes and regrets, about my life, education, and other stuff.?

Honestly, it's not a big deal! You gonna have an exam and you have to start studying without thinking about what will happen the next. Even if you don't pass the exam, you're not goin to die!You will try again!When I was at highschool, I NEVER studied for my exams and actually this was very bad because it made me lose my confidence in a very young age. The reason was that I hated my major. You know in my country we have to choose a general major to study while in highschool. I wanted to go for humanities but my parents forced me to study science. I will never forget I was about to vomit when my teacher was teaching us about the process of digesting a food.Any way... I thought I was a symbol of failure when I was at highschool. But all of sudden I decided to change my life.I changed my major, studied very seriously and could enter university and study literature.You know what the key to success is? Not thinking about what other people are doing, what other people regard as success and how they would judge me. That's all.you might enter university 3 years later than your friends, but you might be the happiest one.and this is what matters.
