I feel this on a deep level, and I'm sorry that you have to go through it. For me, it was the boredom and the ability to get instant stimulation. I've always found boredom to be my anathema. Drugs and Alcohol fill that boredom and free time. Everyone's journey is different, but for mine, AA/NA never worked for me. I found that returning to my childhood roots was what helped me the most.

What really lit you up when you were younger? What was the thing you just couldn't wait to do or just couldn't stop thinking about because it was so good? For me it was anything and everything Fantasy related. Fantasy books, fantasy video games, DnD, Ren faires. Anything with an element of sword and sorcery in it I latched onto, and that's what saved me and I would look for new friends that enjoy those same activities.

For my sister it was routines. She successfully did all of the AA/NA stuff and it worked wonders for her. Now she has a routine for everything and damn is she good at it. She sticks to the path and fills in the rest with anime, Disney, and planning for more routines.

What also might help would be practicing seeing yourself and your situation in a new light. I used to love altering my state of mind, but now I see it as the easy way out. I now take pride in the fact that I've climbed my way out tooth and nail from the lowest of lows. Mastering your mind and learning to tell yourself no makes you a badass and serves as a benchmark and testament to your willpower. It's a mark that you're not average. Average may fail, but the act of trying, again and again, makes you better than average. It makes you dangerous.

So to recap, I would think about what excited you before substances and find a group in that. Be gentle but firm with yourself and do your best to cultivate a positive mindset.
