I'm certainly not a doctor, but at the same time it's trying to keep them speaking about it, and open. Isolation is something that draws them further inward and makes them also think there's no other option.
That is the timeframe when usually hope.... As long as you can try to preserve hope. Hope is the main thing for these people. If they have hope, they can go on another day. If they lose hope...you don't have much if you don't have hope.
As far as advice that I would give, keep the communication as open as you can, so that person knows they can speak to you about it and they don't have to feel judged. Especially for men, they're used to being, in a lot of cases, the main salary of the family. They're used to being the ones taking charge. They don't want to feel weak or unmanly.
Like I said in the video, this is not about being weak or unmanly; this is a health issue. To me, it's no different than if you have cancer.
