I think the first thing that should be done is to look at the person's physical health. I've had down times, but the ones that have persisted have had (strong) underlying physical components. This is pure anecdote, of course. But I've seldom heard of a psychologist or psychiatrist prescribing and discussing a thorough physical. (I am familiar with the "you should get some exercise" mantra; however, if there is a physical component including one that gets in the way of this, it seems this can all too readily turn into a guilt trip for the patient.) Maybe it's different in other countries. I hope so.
