The National Institute on Mental Heal under BPD has a very insightful overview of this condition also commonly referred to as an "emotion dysregulation disorder." This information is not intended for the lay community to diagnose themselves, friends, and/or family.
Thank you for your question.

Dr. Martinez 

You mean, how would personality disorders be expressed in the mothering role? Rages alternating with sweetness; narcissistic behavior in which it’s really ‘all about her’ (the child’s accomplishments or failures are seen as the mother’s) – these are the most common. Try reading a book on personality disorders and you will likely find all the information you are looking for.

Peace,

Dr. Marian Shapiro
