I'm a psychotherapist. I trained for three years and am registered with the BACP.
I don't understand quite what you're so irritated by in your OP.
Gaining insight into the underlying emotional and psychological drivers for the way we think, feel and behave can be transformative and free us up to see ourselves in completely different, more positive, compassionate ways.
I have clients come to see me for all sorts of reasons. Usually it starts out as 'I'm just a bit anxious', or 'I feel generally low in mood', or 'I can't control my anger'. But with the right sort of inquiry, the layers are slowly peeled back to reveal deep wounds such as trauma, bereavement, and childhood abuse and/or physical or emotional neglect. Emotional neglect is one of the most insidious ones because people can believe they grew up in a 'happy' family. But when you look further into it, there can be a painful realisation that while all your physical and material needs may have been met, in fact none of your emotional needs were. That can lead to an inexplicable feeling of abandonment that is carried through into adulthood and re-enacted in relationships.
People carry so much. And when they're stuck in the same pattern, wondering how to make changes, having an objective person who is not emotionally invested in you in the way that friends and family are, can be really helpful in guiding you through asking those difficult questions. Often we are far too close to the wood to be able to see it for the trees.
It's really not unusual to get to session eight or nine talking about general anxiety or anger, or whatever the presenting issue is, and then the client will disclose that they were raped at university, or something similarly awful and shattering happened to them. Then things start to make sense. The pieces fall into place, dots start joining up, and the real work of healing can begin.
It's a genuine privilege to do this work and I don't know why an individual's process of better understanding themselves would invite any kind of judgement.
Perhaps those who would judge find the idea threatening?
