I would like to give my 2 cents.
You played bad move since move 5....... d5???
Those moves are suicidal if you face stronger players. Reasons,
1. You are behind in development ( as you are black)
2. Opening the centre just boost the activities of opponent pieces which are already developed.
3. Psychology tips-- Everyone would like to attack and win in every game. But it is impossible in many situations. As black, play very carefully until you develop all pieces ( up to move 10, 15 etc). Most opening for black are defensive just to minize the development advantage of white.
I don`t think d4 was the bad move in this game. My opponent played a slow move so he didnt have development lead anymore. But you are right about 3. Since I had just won some nice games and gotten my rating to 1559 I felt like I could play more aggressively and recklessly. I didn`t stop to play a prophylactic (defensive) move and from there I gave away too many tempi and put myself in a bad position.
