yep, I played well in the beginning, only to screw up in the end... I am really ashamed of this game. But maybe posting this will help me learn

7. Qd3?
This does not get anything for white. In fact, it hurts! Now black can play d5 and get active play going...
7. 0-0?!
Not terrible, but the immediate d5 was better
8. 0-0?!
White had a chance to get an advantage with c4
23. h5? White is clearly not taking the danger seriously
25. Rxd6!! This allows black to get a pretty good advantage
26. exd6??
terrible. White had to play Bc3 Qb6 cxd6 Bxc3 Rxc3 Qd4! Rcc1 d2! Rcb1 Qxd6, even though this leaves black with a substantial advantage. White's rooks are terrible and although he is an exchange up, his rooks are doing nothing while all of black's pieces are beautiful.
29. Bd1? this makes the win easier
30. Rd8?? this basically throws away the win. Black should play Qa5! where the double threat of Qh5+ and Qxc7 is too much for white to handle.
31. Qd6? falling further into the hole. Black had a completely won position, and he blew it!
...Rxa7 Rxd7 Rxd7 Qxd7 Rxd2
Ok, now with good play from both sides the game SHOULD be drawn, but further slips come due to time trouble.
39. Qe3? Black's last chance to secure a good game was with 39. Bd5!
40. Bh4?? it ends here. Black is now officially lost.
