I don't have time to go thru your game in detail, but you might want to pick up the book Logical Chess: Move By Move, by Irving Chernev. It explains, literally move by move, what you need to be thinking about at a given moment. That book really got me thinking about my opening moves. I was losing too many games in the first ten moves.

There is another book, Understanding Chess Move by Move by John Nunn that is also highly rated. I've not read that one, but you can read the reviews of each here:

Get one of the two books, at least. Then play through some games and pay close attention to the reasoning that lies behind the first ten or twelve moves in each game. Beginners tend not to think much about the opening moves, and they doom themselves before they even realize it. I know this from experience! Pick a white and a black opening and stick with them for awhile (like a year or two or three or four) and you'll start to understand what works and what doesn't.

If you're losing a pawn by the fifth move or if you are about to lose a knight or rook by move 7, you've made a mistake already and need to be thinking more about the consequences of your moves from the very beginning. Good luck!
