Bad mood :-(

what a bad week!
This week is one of the hardest week of this term, it's is full of exams, and this put me in a bad mood. I don't know why I'm always stressed by this. I spend all my time studing and sometimes I trend to be with a bad behaviour with my friends and my family. So I will just try to calm my self, and to not be pessimistic and let the time pass.
I think that I just fear to repeat this years, I'm not sure that my notes are good. But whatever because I think that I'm able to win, I have an objective an di wiil keep it .

Aparently, peolpe see mi like a very calm and racional person but sometimes I can be the opposite .
As we know the apearances can be undependable
