im loosing? right?

there really is no need to analyze this game. I'd say challenge an 1100 or 1050 and if you lose, post it and we'll take a look at it....This guy played with no rhyme or reason, and was a total hack. That last move he made, what was he THINKING? I really believe people need to study the basics of the game before thrusting themselves in online play.
Good job on the back rank mate, those always feel great dont they

if I were you i may have gone 6. e4 he'd probably go 6. bg6 or something and then you go d5 - complete center control against a terrible setup on his end...then probably bring out nf3 and castle shortely thereafter..

Man 800 rated players are really bad!
Asking for help is the best move you made in this game.
14. Nd4 I now start an attack with my knight. - YOu cannot attack with just 1 piece when there are still so many pieces on the board. YOu might consicer working on your piece coordination.
Take more time to look at your position. I think this was a blitz or bullet game. Stop playing these games all the time until you get better at chess in general. I see you have played a few online chess games. And that your win/loss ratio is about the same. So that means you need to improve the basics.
You'r right. If you opponent had played even slightly better, he would have won.
