It sounds to me like it isn't the breakup itself causing the feelings of loss n emptiness but rather an irrational feeling of abandonment that often occurs when a relationship is severed either by the person or their partner if the person deals with borderline personality disorder in their life as well - i know this because it is something i deal with, another part of it is self-blame for the relationship ending and ultimately spiraling into suicidal feelings or actions - so i want to ask you, is this something you too deal with? Borderline Personality i mean? The reason I ask is because if you do, the ways in which others who do not deal with Borderline Personality Disorder, handle and deal with the stress of a break up is usually quite different, as are the ways that create a healthy healing process.
