Looking for support/check ins

I'm 25 and have been consuming daily for almost a year and a half. It's gotten up to a point where I now start with my morning coffee and smoke more over the day. I'm also in the final phase of my Master's studies and life has seemed to slip through my hands completely. Every time I'm feeling a bit of stress, I go take more. I also work a warehouse job part time and all of it just seems to take a toll on me mentally as well. I want to stop this and actually spend time on the life that I want instead of just suppressing every emotional inconvenience. I've made a decision today to stop and will try to check in here everyday. I'm also looking for advice about dealing with cravings as sometimes i start rolling as soon as I have a hint of distress. Thank you for reading this.
