Mattie, my H is in a similar sitch---slightly depressed for a long time, then w/ MLC and breaking off the A so depressed our c sent him for an evaluation right away.
Maybe your c wanted him to read up on depression before the consult?
The book I got was "Change your brain, change your life." It covered a lot of brain misfirings and various treatments, from meds to nutrition to behavioral changes.
