I would have thought GN has it pretty much bang on. Without reading the regs specifically, I can't see the CAA eventually refusing a licence with what you describe. Good reason for original episode, good response to management (both psychological and chemical) and a long period of drug-free stability since. They may get a bit snotty about not having been told but I'm sure that can all be sorted out eventually
I'm sure a response from a current (as opposed to an aspirant) AME will be along soon
