I just cant go....

So here it is, my flight is tomorrow at 13h15- confirmed.. and I even chose my movies and books I want to see and read during those 9hours of flight.. but.

but...

but I am NOT going anywhere...
seriously, instead of packing my suitcase now Im sitting at the window and I just cant go there..
I just cant..

its not even the flight that stops me from going (as I said- ticket is booked and I can have alcohol on board so my "illness" can be easily cured..), its not even the fact that I still dont know what Im going to wear at the rehearsal dinner....

I just cant go because of my great university:

I still dont know my final result of my essay and I just cant be in the other country when this decision is being made..
what if I made a mistake in my application form and they will refuse me??
what if instead of "Mademoiselle" I put "Madame" and they would ask me to show them specific documents that I am married??(I am not... so see the first "what if")
what if they just want to call me for no reason but once they learn Im in States they will feel soo jalous so they will refuse my application??
what if I got into and I won't be the first person to learn that???
what if....
what if....

and Im still terrified by planes...
