I agree that the situations are individualized, but we can certainly have something along the line of first aid skills or perhaps maybe just talking points.
For example:
'Hope and meaning can be in the local, right?'
'Zoloft helps some people. It all depends on someone's biochem. And if someone's not helped by one medication, they're sometimes helped by another.'
'Lack of hope for the future, can be a combination of the philosophical, the social, the situation, the biochem, all of them and more'
and something my doctor told me: 'one study found that depressed persons are actually more realistic about the future than non-depressed persons' This guy was not a psychiatrist, but rather an internist, that is, basically a general practitioner. Somehow this cheered me up a little! Maybe paradoxically. Maybe that he wasn't going to automatically dismiss everything I had to say. PS maybe for action toward the future, we human beings need a bias toward optimism.
