Do you have to have therapy to address past trauma in order to recover from depression and anxiety?
Given this is a column about therapy, then of course the answer is yes! Actually, the answer is that it depends, but I'll get to that later...
Firstly, it depends on how you define "trauma". Usually, people think of it as a threat to life and limb: Getting shot at, beaten up, raped, surviving a plane crash... these things are undoubtedly traumatic, but a useful definition of trauma is one which focuses on impact: Trauma is any event that overwhelms our capacity to cope emotionally.
It's also true that exceeding our capacity to cope is affected by both our capacity to cope, and the intensity of the event. We see this in more obvious trauma all the time. Not everyone who survives a plane crash or goes to war is traumatised by it.
This is also true of childhood. All sorts of things impact a person's ability to cope: Genes, temperament, and the quality of early bonding with parents. All these vary from child to child, even sibling to sibling.
