Mental heath issues can take a backstage role when the action ramps up, or drive the action itself.
Depression that totally incapacitates a person is hard to write, for reasons mentioned above. But, depression does not equate to loss of will, always. Bipolar behaviour can possibly drive a plot easier, as there are more dynamics to play with. Psychotic incidences are ripe material for writing, in my opinion.
I think that mental health issues can make a character richer. Also, since a lot of people have, or know someone who has had these kind of problems, it makes them relatable. If done right.
