Several of your recent rapid losses (which are the only ones that matter until you learn more) were by either resignation or abandonment (abandoning is effectively the same as resigning, except it’s worse, because you could get penalized by being paired only against others who do it a lot). At such a low level, you need to keep playing even if you are behind, because others will also blunder. You weren’t even losing in most of those. Bullet will make you worse, because it teaches you not to think.
Write if you think you don’t deserve to always lose.
