I was diagnoise of having borderline personality disorder by a psychatrists at the mental hospital and I must say that I'm pretty much a nice person. However I do have my moods! Mood swings are apart of the disorder, especially in females such as myself... When a woman has her period... it can be extremely diffcult with the person to be nice.. It is a fact that most women who get admitted to the hospital is suffering from PMS and have a personality disorder. All I can say is to UNDERSTAND the disorder and to not take anything personal from someone who suffers from it.
