Treatment is very defined: You are in a difficult spot, you need help, you go to the professionals, they help you. It might mean going to rehab, leaving your current job for a while or even moving home.
Recovery is the rest of life, its the bit that happens after treatment. I once heard it put like this, ‘if recovery was a train journey from Manchester to London, then treatment would be the taxi ride to the station’, recovery is the rest of the journey.
Recovery is about ‘How do I live the rest of my life with this past experience or risk hanging over me?’
