Confront him, you need to know whats going on. I didnt know they could take your license off you for mental health reasons but it makes sense. If he has signed the documents, the licensing people will go by what he has said, so Im not sure you can fight it unless you get a second opinion (which I know is an annoying and expensive road to go down in Oz). Talk out what you are feeling with him. Im not sure how long you get to see him for but I see mine for an hour so we can really get through some stuff. Tell him your worries about losing the license and or being triggered. Im glad you are on the up though, at least someone is having some fun!
