Ouch, how dumb am I????

I was playing a friendly game with a 1560. The game was 30/10 and it was a closed game. It was a dead draw until I screwed it up. Darn! Any advice on how to have avoided these errors? Thanks. You can check out the game here: http://www.chess.com/livechess/game?id=616459480

Sure.  Don't hang a piece. 

play through a grandmaster(or anyone, it doesn't even have to be a master) game and look at all the threats for each move. when you are playing think "what are his possible captures, checks, and threats" before each move.

Ok.

Thanks for the advice.

You're not as dumb as I am.

I see.

 this is going to make you feel better:

Quit playing chess.

No, I will continue playing chess. Quitters never win!

Yeah.  The main thing is, don't hang a piece.

ok.
