Depression and Self Pity

Why is it that so many people are beginning to believe that depression doesn't exist? They think it's just people being selfish or making it up as an excuse. A lot of them, when someone argues, will point out the similarities between actual depression and just self-pity. Think about it though. There are tons of similarities between humans and dolphins. But would you ever say a human is really just a dolphin by a different name and that humans don't really exist? Or that humans are in invalid species or just an excuse not to do things? No! Don't be so stupid! Depression is a mental illness. It's diagnosed by doctors. There's medications for various types of it. Depression does exist. It's not just an excuse. It's not an excuse at all. It's real.
