If depression is the emotional expression of the immobilization response, then the solution is to move out of that state of defense. Porges believes it is not enough to simply remove the threat. Rather, the nervous system has to detect robust signals of safety to bring the social state back online. The best way to do that? Social connection.
For people who don’t prefer social connection, I’ve seen that exercise works well

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.
