ADHD or BPD? Why They Look So Similar.

Ever wondered if ADHD and BPD are connected?

These two are often confused because they share similar symptoms. But behind the labels, there are important differences in how they affect the brain, behavior, and relationships. In this episode, we explore where they overlap, where they differ, and what actually helps when you’re living with both.

Trigger Warning: We mention sensitive topics. Take care and pause if you need to.
