My Biggest Screw Up In Chess Ever

Hey guys,

So I recently play a game....

It started off really normally with typical opening moves. I tried to fight for some control with the move 10. f4.

After a while, I realized that there was nothing I could do to play on the kingside. As a result, I quickly switched my perspective to the queens side. Pushing my pawns on the queenside, I aimed for a lethal attack. 

It all seemed to be going well so far..

I got in moves like b4 and c4. My opponent was defenseless.

Little did I know what my fate was...
