You moved your queen a bunch of times before your pieces were developed, which often causes problems, and is something beginners are taught to avoid. Too many pawn moves before you develop your pieces can also be bad, but that is less of a rule.
A bigger problem was that you dropped a bunch of pawns, then let white open up your king's pawn screen with 15. nh5. You open up your king position, bad things can happen.
You need to work on the basics -- developing all your pieces quickly being the most important, and your tactics. Improver your tactics with the tactics trainer here or at chesstempo.com.
Lastly, if you have learned about the "sicilian defense" and were trying to play that, forget it for 6 months. At your current strength, you need to focus on developing all your pieces as quickly as possible and learning some tactics rather then trying to memorize the moves of an opening.
Hey fellas,
I was playing a pretty intense game in my opinion as black, and as always and as a beginner I made quite a few blunders. I would appreciate it if someone could just skim through any the moves in this game and see what they would've done instead, or what I could improve on
