Ridiculous push?

[11t]

I realize it was early in the levels but I wanted to just take down the pot instead of dealing with the weak raising that was going on.

Am I a moron?

P.S. Could this be a form of tilt? I lost a pot with KK the hand previous to this.

I don't particularly mind this push. Most of the time you pick up a good amount of chips and in those few cases where you are called you have a coinflip at worst.
