Awesome, Kevin -- sounds like you're well on your way to consciously creating a more empowering social environment.
When I was 19, several of my friends were criminals. I was even good friends with a drug dealer. Fortunately I was able to see where that environment was leading me and got out, largely by moving to a new city, making new friends from scratch, and reconnecting with my best old friends.
Sometimes you have to take a step backwards before you can take two steps forward. The new reality you're creating will be so much more "you" than the old one.
I'm really delighted to see that you're making so much progress, especially with dropping alcohol. Nicely done!
