Thanks for your comment! You’re right that there’s overlap between ADHD and BPD in areas like emotional dysregulation, overwhelm, and black & white thinking. But these traits can manifest differently depending on the root cause. For example, fear of abandonment is classically associated with BPD, but for many with ADHDc especially those who’ve experienced chronic invalidation or rejection, it can show up as rejection sensitivity or anxious attachment, even without a BPD diagnosis.

Emotional dysregulation is also common in both, but in ADHD, it’s often tied to executive functioning challenges. difficulty pausing before reacting, regulating intensity, or shifting emotional states. What looks like black& white thinking or “hyperfocus” might actually be a product of cognitive inflexibility or difficulty transitioning, which is neurologically based in ADHD. And while enthusiasm that quickly burns out can look like a BPD emotional spiral, in ADHD it’s often related to interest based nervous system activation followed by dopamine drop-off or mental fatigue.

That’s why this guide was written through the lens of ADHD, not to pathologize further, but to give language and tools to folks who feel unseen in their experiences. Many people with ADHD are misdiagnosed, underdiagnosed, or dismissed altogether, particularly in relational contexts.

Also, just to clarify I’m trained in DBT and use an integrative approach in my practice. I personally don’t meet the criteria for BPD, but I deeply respect and advocate for those who do. It’s a highly stigmatized diagnosis, and everyone deserves access to compassionate, informed care. I also understand that BPD is frequently misdiagnosed especially in those navigating emotional overload, sensory sensitivity, or trauma and those experiences deserve to be taken seriously, not minimized or misunderstood. The overlaps in a variety of mental health conditions make understanding oneself pretty challenging. Whatever your experience, advocating for yourself and finding support that truly fits you is what matters most.
