Many people who have seen our website have written to us describing their self-centred horrid parent with clarity and insight. Some, however, have gone further and stated that their parent hadNarcissistic Personality Disorder or Borderline Personality Disorder.
It is totally acceptable for a qualified mental health professional to diagnose a patient with one of these disorders, and some horrid parents fall into this category. But anyone who does not have a professional qualification should exercise caution. A horrid parent can function well socially and hold down a good job while still behaving badly with their child. Something that makes it difficult for a professional to diagnose a mental health disorder.
It is understandable to want to neatly categorise what is wrong with your horrid parent. Not least because you need all the help you can get to make sense of what you have been through.
