I'm going to fail

I just know I will. This is my second attempt at these life changing exams and I just know I won't do good. I'm trying so hard every single day but I'm terrified of seeing the disappointed looks on everyone's faces like the first time and I just can't bare to witness that. I can't even breathe properly writing this, I just have thus horrible gut feeling that everything will all just cruble down. My relationships, my education, my future, my life, all of it. Everyone I try to talk to about this just gets angry at me for feeling this way and tell me to read more, and I can't imagine how they would react seeing my grades in August. I can't do this.
