Have Faith
I've been through what you're going through....years ago. I quit a liter a day habit cold-turkey....not recommended...I had become sick of what my life had become. I went through the worst 72 hours of my life during that detox. After that, there was still the residual physical and psychological pain to deal with. Eventually the fog cleared, but through it all I never lost my focus and commitment to stop being a slave to alcohol. Through it all I never looked at others or how others were doing. My measures of success were mine and all internal. You can do the same. Get your mind clear, set your own goals, and take the small steps necessary to reach them. Above all, learn patience. All of this will take time.
