ouch! My head hurts!

Ok guys i tell you i'm a completly noob about chess theory. I only play using my "personal positions experiences" some personal tactics and psicological harassament. Is always intresting and funny to me analyze positions and games, so I decided to improve playing in order to play at the same level of people who likes chess as muck as I like it.

SO,

I got this problem and my head hurts!, I can't find any solution and I'm really thinking that I'm gonna loose this game 'cause I did too many mistakes (I got a couple of chances) my attack was too bad. What do you think about it?

Sorry,I'm not asking advices to next moves but to past moves!

It's one and the same really -- advice on your past moves can give you insight into your current position.  Wait until the game is done and then solicit advice.
