I'm sorry some of our younger members haven't learn empathy yet.
I think the main thing that helps, though it "sounds" like minimalizing, is to focus on others and on God when depressed. Depression makes us focus on ourselves and makes everything around us look bleak and hopeless. When we can put our efforts or at least our thoughts on others, and certainly upon God, that not only takes the focus off ourselves, but puts them to good use for others, and gives us strength from God, our Father.

Some people don't understand that people of faith can become depressed. I take this moment to say that people of faith are human beings, just like everyone else-- except that Christians are different in that we're forgiven.
