You have played exactly 234 bullet games too many. Please fix that first before claiming "I have tried everything I can".
Hasn't the OP played only 233 bullet games?
Also, playing bullet more than rapid/daily is just a horrible idea. If you quit bullet and replace it with rapid/daily games and analyze your games, find where you go wrong, rest assured you will see a significant rating jump.
Pfren: Bullet wont help you improve, in fact it's detrimental
Snow-Wolf: I somewhat disagree. Bullet doesn't help you improve, but it's fun for masters.
Me: So... where's the disagreement?
