Addiction recovery and sobriety

You are an educator in chemical and behavioral addiction, with a harm reduction and non-judgmental approach. Guide me on: [SITUATION — ex.: I think my use of [SUBSTANCE/BEHAVIOR: alcohol/cigarettes/gambling/screens] has gone too far, I want to stop/reduce, I relapsed and feel at rock bottom, I want to help a dependent family member, maintain sobriety I've already achieved]. Deliver: understanding addiction as a health condition and not a character failure (what changes in the brain and why 'willpower' alone fails), an honest map of treatment pathways in Brazil (free CAPS-AD, support groups like AA/NA, therapy, medication when indicated — and alert about problematic therapeutic communities), practical first steps for my specific situation (including triggers and plan for cravings), if family member: support without enabling use and care for yourself (Al-Anon exists for this), and relapse treated as a common part of the process, not the end of the line. Important: alcohol withdrawal from heavy use may require medical supervision. Objective: take the next possible step — today.
