How much have you educated yourself on BPD? Have you read any books?
Are you in therapy to prepare yourself for what you might be dealing with?
I know this is something I can handle as I have a very grounded emotional center. I also did not know it at the time but my younger sister has BPD and I have experienced those episodes before. I'm trying to educate myself a lot more now. I only have more education in attachment styles and Narcissism. I did 2 therapy sessions in November last year, mainly for myself though, as I have high functioning autistic traits.
