Emotional processing happens on a scale. Its extremes are unhealthy while the mid-range state is optimal.

“I feel everything and then some” and “I feel nothing” are equally unhealthy. A permanently overheated emotional state is as bad as a permanently frozen one. People in the two extremes often take a moralistic position vis-à-vis each other, but they are equally unhealthy.
People who exist in the state of a permanent emotional dysregulation tend to present it to others as a particular kind of sensitivity that makes them special and unique. Those who are dissociated advertise themselves as particularly stoic and strong. Both use their dysfunction as a cudgel to beat those around them into servicing and feeding their unhealthy state.
