To be honest I think every one has personality things that impact upon their BP, whether or not they have a "personality disorder" these are what makes our triggers our triggers. The more you can learn about why your react the way you do, at home, at work, with loved ones, the more you can take control and not be upset by these things. BP has the potential to make any reaction so much worse and out of control than if there was no BP.
Please go easy on yourself, this is not an easy journey and it is ok to take time away from it when it gets to hard.
Love and prayers
