big things to explain would be the inability to regulate emotions, how extreme those emotions can be, how easily they can be triggered and how you handle them. Then there's the fear of abandonment which is one of the biggest triggers.
"The one word that best characterizes borderline personality is "instability." Emotions are unstable, fluctuating wildly, often for no discernible reason. Thought processes are unstable—rational and clear at times, quite extreme and distorted at other times. Behaviour is unstable—often with periods of excellent conduct, high efficiency and trustworthiness alternating with outbreaks of regression to childlike states of helplessness and anger, suddenly quitting a job, withdrawing into isolation, failing."I'm not sure what else to say. BPD and simple don't really go together. I'm sorry.
Are you really going to judge me because I have a personality disorder...
