>>7050732Put yourself in their shoes. If someone was talking to you, and you could read between the lines that they were depressed and needed support, would you help them? Most people won't because of a few reasons:
You can never know for sure if the person you're helping will actually change. Depression is fed by bad habits and a failure to socialize well. These can both be fixed, but unless someone is determined to improve their own life none of your efforts will matter. Also, if they could have, they probably would have already.
It takes a lot of time to help them that you could be using to either have a good time or fix your own life.
It's not fun to talk about depressing stuff, especially if you're in a good mood. Nobody likes a downer, and telling people you're depressed makes them want to deal with you even less.
Finally, we're wired to not deal with those problems in other people. On a society-wide level, depressed people represent nothing more than a threat to the people around them and the state. Remember, we're still competitive animals, and somebody falling behind in the race is ok until they start killing people. It's more complicated than that, but think of it this way, as long as you show up to work nobody cares.
