Thank you for posting this. It warms my heart greatly to know there are other players like me out there. If it makes you feel better, just know that I've been there with many 1v1s exactly like this and I've got aim assist... (I play on XBox.)
To quote, as is appropriate with all things, "The Big Lebowski"
Sometimes you eat the bar. And sometimes the bar....well, sometimes the bar, it eats you.
Wishing you many future fights where you eat the bar.
