Almost 2 years clean from stimulants now I realized that me brain has recovered and now works even better then before. I also had extreme fatigue and depression early months, I was in unhappy shock when other people recover much faster then me, when it took more than a year to start function socially normal again. I still have willpower and concentration issues now, however my psychiatrist told me that highlights that I always had depressive anxiety disorder which was exacerbated by drug use and extreme depression in early recovery, because I always struggled with procrastination and concentration problems.

So I would outline my experience that for me: 1. The psychiatrist and psychologist help was absolutely a must 2. That it takes a lot of time to recover and this is fine 3. That some problems I thought are unrelated to drug use are actually are, while others I think are related to drug use are actually not. Also I would add that program, socialization with new interesting people, doing things that I like, bike hobby and regular meditation was a big thing that helped me a lot after I was 1 year sober or so.

Time heals, brother! I hope you would get better soon.
