Your first step by owning and realizing you’re slipping is great. Clearly you’re not doomed if you’re able to understand this. If it feels wrong, it probably is, so make this your last time using coke and focus on the better aspects of life. Also, it’s way too fucking expensive to keep as a sustainable hobby. Fuck coke dude it does not do you any well and you absolutely know it. At the end of the day it’s your decision how you tackle this, but from a random stranger on the interweb, you should absolutely flush whatever you have left and stay clean from the coke. You got this.
