Work on your tactics. You give away too much material to worry about other phases of the game right now. Staunch the blood flow, switch over to 1.e4 as White and 1.e4 e5 openings (where possible) as Black to get more tactical practice in open game positions, and then work on endgames. Play slow (daily) games if you aren't already, since they will give you time to think things through. (IMO, playing nothing but blitz is counterproductive at your rating level). Those are the things that will improve your playing strength (and results!) faster than anything else. My $0.02 FWIW. Good luck!
Any ideas?
Thanks!
