I once had a patient with a disabling symptom, a fetish which is an obsessive need to touch or photograph or otherwise involve themselves with an object or body part, which can be a woman's shoe or foot, just about anything. Being almost always a male symptom, women tending not to develop them, it reflects early life trauma during which the object involves what has been termed "castration anxiety," the boy's fear of losing his penis. The boy, having seen a naked female and fearing they may lose their penis as he incorrectly believes the female did hers, uses the fetish to symbolize this fear and underlying anxiety. Which tends to persist since early childhood has immaturely developed thinking capacities and is the bedrock of the adult personality.
After explaining the nature of fetish to this man, I advised him to talk to himself: to tell himself that while the fetish helped him when he was a child it was no longer needed. Still, both he and the fetish would remain friends throughout life but the fetish could relax. Using this technique, which contains elements of play therapy with children, his obsession with the fetish disappeared within several months.
Similarly, when one has experienced a traumatic experience, during wartime or after rape or assault, if one tells oneself that the later symptoms were created to help them and not the problem, they are better able to cope. Understanding that the associated symptom such as nightmares are friendly warnings to resolve an unconscious conflict and not an enemy.
So while talking to oneself has a bad reputation, it often being associated with psychosis, it can be healing. But it should be done when alone and need not be spoken aloud.
