Randi Kreger, co-author of the bestseller, Stop Walking on Eggshells: Taking Your Life Back When Someone You Care About Has Borderline Personality Disorder, joins Sisters Cracking Up to pull back the curtain on the wild, complex, and eternally frustrating experience of being in a relationship with someone with BPD.

And that relationship can be with anyone in your life: spouse, partner, parent, boss, or even your child.

What are the hallmarks of this personality disorder? And why do those on the receiving end always feel like they're losing their marbles?

Randi Kreger shares her personal experience with BPD and how it sparked a lifelong interest in the disorder. She has sold over a million books worldwide on BPD, enlightening and giving relief to those who didn't have the words to describe their traumatic experiences.
