Stressed out so I game

I am getting close to finishing graduate school.  I take the comprehensive exam which I must pass to get my degree in less than three weeks.    I have really not studied for it despite knowing the date is getting closer and closer.  Been getting overwhelmed to the point of avoidance.  So I have been playing my games as a way to not think about school related stuff.  I am also working full time and trying to fit in an unpaid internship because I have to earn 500 field work hours to graduate (I have about 220 currently so have a LONG way to go). 

I tried to use my games as an incentive to do something "good" for me by letting a friend hold my Rock Band, Guitar Hero 2 & 3 games plus the two GH controllers (figured he may as well play them if he had them and the Rock Band strat is too fragile to loan out).  I ended up just playing something else instead.  So I am nearly finished with Need For Speed - Most Wanted now.  Only have the last guy (Razor) to beat now.  I have had that game since just after getting my 360 and hadn't played it in quite some time thanks to Oblivion, Bioshock, Halo 3, Guitar Hero 2 and Rock Band getting most of my gaming time love.
