I cant get better, need your help !

I have 2k hrs in csgo (1.2k is actually played, rest is idle)ive been playing for around 7months, and the last like couple months, even though im playing daily i cant get better.There was a time before those 2 months that i peaked around level 7 on faceit and B+ on ESEA, then i entered a slump and dropped to like level 3-4 and been stuck there ever since.I keep playing and playing coz i still love this game, but its not fun when you see yourself stuck in the same level and repeating the same mistakes over and over.Now i got a grasp of my mistakes even though i cant point them out specifically, i used to be able to compete with higher level players but i no longer can.What can i do? Is it normal for this to happen?Should i just keep playing and setup a different routine to improve my aim? When i was a silver and i had shit aim i had a routine of flickshot map, head tracking, and recoil master and it improved my aim to help me get here, but ever since i found FFA DM ive stuck with it.Should i keep doing it or change it? Someone help please ! Best answer wins my redline ak :P
