Play on a smurf until you feel comfortable hitting shots again before you go back to your normal account, that's what I always do
You are probably an agressive player and when you play vs people worse than you it works, but when you play vs better people it doesn't work. Try to play smarter.
learn Ultra Instinct
or get a better gaming chair
it's the game, hitreg and sync is fucked up. nothing you can do about it
i wont tell you the secret to perfect consistency.
its not possible to be consistent on pugs
it's easy to play well when opponent is playing in your hands. But consider things that enemy can do to throw you off. What are the reasons why you play worse? In order to become truly consistent, you have to be prepared for anything that opponent can do.
its probably because u are too dependent on csgo to make u happy. so ur scared to fuck up, making u overthink and fuck up
gotta be consistent irl too
get a consistent sleeping schedule
drink lots of water
its all about your "ready position" - how you sit and hold your mouse. some people have "ready position" window wider and can be pretty much consistent even if they sit lower, higher or in different angle etc. And some people like you or me have the "ready position" window narrower, where even a tiny little detail makes a difference and therefore we are more inconsistent. and on top of that, when you dont feel comfortable you are not confident and you lose focus.
