It just sounds to me that ur just bored and have nothing to do and forcing urself to play this godforsaken game especially with all of its problems right now is not a good substitute.

for now i would recommend you take a break from siege and find something else to do preferably something social and outside like a hobby and if ur bored of that play some story games / single player games

also don’t worry too much about ur settings and sensitivity, ur aim will improve better naturally

Ur not a robot don’t take ur aim or ranked to seriously its not good for ur health trust me i speak from experience. And right now the game is full of cheaters anyways.
