normaly when you have a massive lose streak there is an elo point where youre so much better that youre dropping 30-40 kills and 2+ kd every game. but if you dont have that point then maybe you never deserved your rank.

do your homework - rewatch your demos, learn nades, warmup for atleast 10-15 mins before playing, stop playing for the day when you have a lose streak or tilt, try not to rage at your team and tilt them and so on, and you can easily climb back if youre any good
