i feel sad and soppy

I cried again because of my second intervension as I did for my first intervension. I don't know how many times must I say this but I feel like the stupidest being in Azam. I think I'm not trying hard enough or maybe because I just feel scared of all the other super smart people in my class. I don't know. I wish, I wish that.......I don't know :(
