I'm not sure this is good advice. I have no experience of this kind of thing, but it seems to me that cutting yourself off from everybody who cares about you is one of the worst things you can do. Now you have no money, no friends, no family, and nothing to stop you when you next start to feel like jumping off a cliff.

It sounds like a good start to a story, but bad real-world advice.

I had an ex-gf who worked on a suicide hotline, and apparently one of the most powerful things they had in their arsenal were questions like "Who do you think would find your body?" and "How do you think it would affect them?" and other encouragements for suicidal person to think about how their suicide would affect those around them. If you're backpacking alone in Africa, having taken your leave from everybody in your life two months ago, it seems like there'd be a lot less to keep you.
