My aim is decent and in casual and deathmatch but i literally cannot aim in premier or faceit. How do i fix this problem?

I immediately start panic shooting whenever i see an enemy in premier (12k) and don't even think about aiming properly before shooting. Despite having decent crosshair placement and movement(ik counter strafing well) i feel like i completely forget about those things when i see an enemy and just try to crouch spray and hope i get that kill.

I currently have 560 hours in this game and most of that time being spent in death matches and casual mode only recently i have started to queue for premier and i have bottom fragged in almost every match despite imo having better understanding of game then some of my teammates and higher rating as well.

I have currently set my sens to 1.4 400 dpi which sounds low but i start shaking on this sens as well.

Only thing which somewhat worked for me is that i stopped crouching entirely during fights which forced me to actually aim on enemy's head but even then i shake so much that i just end up whiffing the shots anyways.

Is there a way i can reduce shakiness and stop panicking during engagements? Because i feel like even bots have better aim than me.
