I realize I am overly stressed about my education.
That's awful. Why are you stressed out about your education?
There are many new things to learn, I'm afraid of failing exams
It's fine to realize when you're under stress sometimes. You should talk about to someone to destress.
Why do I have to talk to somebody? Am I not allowed to get over stressed?
You are allowed to be stress but it is good that when you realize that you are under stress to do something about it. You will be able to function better if you learn to manage your stress.
