Stressing out

I'm so stressed out with examinations . makes me wanna kill my self . Why must i fail in this things ? . i keep thinking that i may be an idiot to be failing easy things . Justi hope something will make me feel okay . Because after failing something its hard to get over it . ! Thats what i feel when i got my exam papers . Why can i be like other people who never fails anything and succeed . right now i'm just hating my self and feeling stressed out ! Ughhh !
