I am tired

I don't know why i have taken this, but now i am tired. from the past one and half years i have involved myself completely in this arduous journey of preparing for this exam. i don't even know when i am going to clear this once and for all. all my energy is exausted. don't know to regain it as well.
am not repenting, but airing out my inner feelings. because i am very much aware of my future endeavours.
was worrying since i hadn't written the essay part well. but i know somebody in the universe will conspire for my marks and i will get good one only.
god, please help me out to cross these feelings, am not able to bear one such any more.
now comes the test of personality. i have got to perpare for that also. i just don't understand how a person can decide the personality of other by reading his inner mind, when he himself lack that perfection.rediculous!.
don't know how am i going to be interviewed.but am sure the whole universe will conspire for me and for YOU!
