Summary

If you have ADHD and your emotions feel overwhelming, fast, or hard to control—you’re not broken, lazy, or “too sensitive.” In this episode of Therapy in a Nutshell, I explain the brain science behind ADHD and emotional dysregulation—including delayed prefrontal cortex development, dopamine and norepinephrine differences, rejection sensitive dysphoria (RSD), and why emotions can hit before your “brakes” have time to turn on. Up to 70% of people with ADHD struggle with emotional regulation, and there are real neurological reasons why. I’ll break down: Why ADHD emotions feel so intense and reactive How executive dysfunction affects impulse control, frustration tolerance, and emotional recovery What rejection sensitive dysphoria (RSD) is and why criticism can feel physically painful Biological triggers that worsen emotional dysregulation (sleep, hunger, sensory overload) ADHD emotional “superpowers” that often get overlooked Looking for affordable online counseling?

Always consult your physician before making any decisions related to your physical or mental health. In therapy I use a combination of Acceptance and Commitment Therapy, Systems Theory, positive psychology, and a bio-psycho-social approach to treating mental illness and other challenges we all face in life. The ideas from my videos are frequently adapted from multiple sources. Many of them come from Acceptance and Commitment Therapy, especially the work of Steven Hayes, Jason Luoma, and Russ Harris. The sections on stress and the mind-body connection derive from the work of Stephen Porges (the Polyvagal theory), Peter Levine (Somatic Experiencing) Francine Shapiro (EMDR), and Bessel Van Der Kolk. I also rely heavily on the work of the Arbinger Institute for my overall understanding of our ability to choose our life's direction. And deeper than all of that, the Gospel of Jesus Christ orients my personal worldview and sense of security, peace, hope, and love https://www.churchofjesuschrist.org/comeuntochrist/believe If you are in crisis, please contact the National Suicide Prevention Hotline at https://suicidepreventionlifeline.org or 1-800-273-TALK (8255) or your local emergency services.
