When people are told that depression is an aberration, we are telling them that they are not part of the tribe. They are not right, they don’t belong. That’s when their shame deepens and they avoid social connection.
And that’s not the only reason people are made to feel they’re not part of the tribe, that they don’t belong. There are many things in this modern (post modern?) world that cause us to become alienated from other people, even and especially those in our own community. The nature of community itself has changed. Many relationships and social institutions feel more tenuous or impermanent.
It’s a vicious cycle: people feel alienated from others, it causes them stress, the stress causes anxiety, that leads to the immobilization response and depression, the effects of the anxiety and depression cause people to become further alienated from others, and the process accelerates and perpetuates.
