I bet you will be doing OK in 6 mnths. Lifting heavy, sunlight, Lions Mane, Nutrition and Meditation can speed up things and I bet make you better than baseline in about a year. For me, Keto helped a lot.
I had something similar going on 3 years ago and im truly thankful for the horrible state I was in. I realized to course correct and do my own thing and now I feel better than I have ever done.
Reading is another great thing to do. When you're done with impulsive pleasure seeking, it is only right to start consulting the ancient wisdom.
Without meaning it will be difficult to stay sober. 12 steps is great.
Good luck brother
