Often individuals who have experienced insecure attachments in childhood have high shame and self-criticism as companions in adulthood. The dominant role of their overdeveloped threat and protection system means that they have an underdeveloped capacity to use the soothing and safety system, whose function is to allow them feel safe and cared for.
In order to communicate very openly with the world, you need to develop fundamental trust. This kind of trust is not trusting “in” something, but simply trusting. It is very much like your breath. You do not consciously hold on to your breath, or trust in your breath, yet breathing is your very nature. In the same way, to be trusting is your very nature. To be trusting means you are fundamentally free from doubt about your goodness and about the goodness of others.
