A good attempt to explain.

‎"The experience of infertility plunges people into contact with the outermost reaches of their humanity. Infertility is a profound crisis that threatens identity, relationships, and continuity. It threatens one’s sense of the world, it disturbs beliefs and assumptions, and it takes away safety and security. It is an emergency that uses up coping skills, and depletes resources; people start to run on empty as their chronic stress levels move into the area of trauma. Infertility can shut people down emotionally, it necessarily limits and narrows; people are functioning in “emergency mode,” a black and white vantage point that oversimplifies for the purpose of survival. This is not the best place to understand the complexities of human interactions, or the perspective of the “other;” this is a time to survive, and everything else may feel inessential." Anne F.
