I wish to die! :'((( i'm cursed!?

Well the simple answer is you are cursed if you believe you are. The only way curses work is to make the person cursed believe it. And then every bad thing that happens can be blamed on the curse. So deal with the curse separately. As to the exams and such. Get to a counselor soon. Explain your situation if he/she doesn't already know. Get doentation from the doctor if needed. If you are such a brilliant student the powers that be should bend over backwards to help. But if you keep believing this curse stuff all that you have done will be lost. So byp the curse for now and get busy with what you can do with what you have. By the way the zealous Christian fervor with with the other answerer answered may or may not apply. Look at it this way. You can always take that way out. But it is final and complete. You will never know if all your work was successful unless you keep trying and I am thinking you are not a quitter. Get busy you can do it.
