Psychiatrist tells patient "You don't have a Life"...how can this be good for a patient?

A patient is told by their Psychiatrist that "You don't have a Life" ! This is after 3 years of consultation for, PTSD, Avoidant Personality Traits and OCD (checking / obsessive doubt). What possible Theutic value could this be for the patient ? What should the patient do when they feel hurt and alienated by this remark ?
