Drawing on large family and twin studies, we discuss what research tells us about heritability, why no single “BPD gene” exists, and how hundreds of small genetic variations interact to shape emotional sensitivity.

You’ll hear how conditions like depression, bipolar disorder, and PTSD share overlapping biological pathways with BPD and why this matters for understanding vulnerability without reducing people to their DNA.

Through Ana’s story, we bring the science to life: a young woman whose family history of mood swings, depression, and emotional volatility forms a thread in her own struggles. Her story illustrates that genes can load the gun, but it’s the environment that pulls the trigger.

This conversation highlights one central truth: genes are not destiny. Sensitivity can become risk in chaotic contexts, but it can also be a source of depth, empathy, and strength in safe and supportive environments.
