"Think", "Wish". I guess they are interchangeable.
Seriously though.
9000 hands is NOTHING.
If you are going to quit, then quit.
Why not go into pokertracker, and go through EVERY hand with a fine tooth comb.
There is a "How should I have played this hand" on this forum, and on many others.
Post any hand that you aren't sure if you played correctly.
Pay close attention to all the hands that you lost large amounts on.
Did they suckout? Did they have the odds to call? Did you misplay it?

Chances are you still have ALOT to learn.
I Know I do.

Remember, Nobody likes a quitter. Well, Not sure if anybody liked you to begin with, but quitting never helps.
Why not take a break, and STUDY?
It can't hurt.

Without seeing specifics, nobody here can comment on your actual play.
How about this:
Post EVERY SINGLE A-A hand in your database (seperated by level).
Losing that amount, leads me to this guess though:
You are either letting people in too cheaply when you hold AA, or you are not raising anything but TOP hands and are winning small pots with AA.
Also, are you able to fold AA when you run into a bad flop, or turn?

Good luck.
