dudddde, chill out man!
your attitude seriously needs to change, i would feel sorry for the poor sod who has to sit next to you for hours on end with you being like that.
whatever your personal circumstance i dont think you should bring it in here acting like your better than us we re all in the same boat ok.
if there are personal issues affecting you i would sort them out before pursuing your career further.
ps. read the links ppl have sent you that will help you!
