The hard part of depression is actually talking to anyone because, our society has educated us to stay around happy and positive people.
We're told, an hour of your life is wasted around a negative person, so spend every moment with positive people that are uplifting and make you feel happier.
But then everyone says, why don't people with depression talk? Because as soon as you try to, most people try to distance themselves from people who they perceive as negative. You feel impolite talking about your depressive feelings and they often try and change the subject and you can't blame them and for most people, just a subtle hint that they're uncomfortable and you close up.
Then some well meaning but unskilled people try and fix your problem with cliche's because they don't understand the difference between depression the illness and depression as in oh i'm sad because my dog died etc. They say things like, "pull yourself together', "man up", "get a grip", "everyone gets depressed", "there are people worse off than you", or just make light of your issue as in naa your over reacting, our family isn't like this, your brother is tough, what's wrong with you? now get back to work .. etc, this has the effect of ensuring that they person never talks about it again.
So then the person suicides and everyone says omg why didn't they reach out, why didn't they talk to us all? and they often tried. Society just isn't geared towards helping depressed people. Reminds me of a suicide letter that a guy wrote before he walked across the Golden Gate Bridge to jump off. He said, if one person coming the other way smiles at me, I won't jump.
