Attachment wounding can be hard to define. It is usually not defined in a "one moment in time" scenario. Rather, attachment trauma wounds are usually a composite of childhood experiences that involve emotional or physical neglect, abuse, abandonment, insufficient attachment to (and/or sudden separation from) a consistent primary caregiver.
Left untreated, the wounding can stay with us and impact all areas of life. For example, the survival strategies we learn as children can be carried over into adult relationships.
A person suffering with untreated trauma or attachment wounds may suffer with substance use and/or be diagnosed with ADHD, OCD, ODD, Depression, Anxiety, a Personality Disorder (usually Borderline and/or Narcissistic), or other DSM specifier.
