My psychologist says i show signs of abuse even though that's never happened. what could he mean?

Beware: What you say worries me. There is a school of "mental health care", more popular in the 1990's, that urged troubled people to try to remember forgotten abuse, primarily sexual. Controversy remains, but i think most physicians consider it non-evidence-based and to have caused tremendous harm both to patients and their families. Consider talking with an evidence-based psychiatrist about all this.

Sometimes we : Repress memories of abuse. When this happens we don't remember what happened but can show symptoms of abuse. It is the unconscious mind's way of trying to get help for unfinished busines. Keep working with the psychologist and see what you discover. Sometimes dreams will help you begin to remember.

Repression : Repression is a defense mechanism that often is presented by people who have experienced severe trauma. Repression means the trauma is pushed down so far into the unconscious, that it cannot be remembered at all. In theory this, I think, is what your doctor is referring to.
