Good luck Pengola. There's an increasing awareness about trauma and substance misuse. Dr Gabor Mate is another person - Hungry Ghosts is about exactly that, though it's quite hard going. He's done quite a lot of Podcasts though, if you search his name the Tim Ferriss podcast or Dr Rangan Chatterjee's are good examples.
Stephanie Covington in the States has helped to pioneer some work around this too, moving services from "what's wrong with you" to "what happened to you" which is much more useful around understanding your journey and how to recover. I think people who haven't been in severe emotional pain can't understand its intensity and how you'd do anything to make it go away. Recovery is more akin to how you'd recover from chronic physical pain than it is being able to think your way out of it because of how our brains are constructed
