The Overstimulated Heart: Understanding the Emotional Life of Your ADHD Brain (The Overstimulated Series)

You've been told your whole life that you're too sensitive, too emotional, too reactive. Every time you spiral after a text that goes unanswered, every time criticism lands like a physical blow, every time you find yourself completely undone by something no one else seems to notice, you've wondered if something is fundamentally wrong with you.

It isn't. You have an ADHD nervous system. And no one ever gave you the framework to understand it.

The Overstimulated Heart is the guide you didn't know existed. A clinically grounded, deeply compassionate roadmap to the emotional life of the ADHD brain. Written by Dr. Rebecca Lewis, surgeon and women's health specialist, this book explains not just what is happening inside your nervous system, but why, and what you can actually do about it.

Inside, you'll discover:

• Why rejection hits so hard: the neuroscience of rejection sensitive dysphoria (RSD), why disapproval triggers a pain response that feels completely out of proportion, and how to stop letting it make all your decisions
• What emotional flooding actually is: why you lose access to your regulated self mid-conflict, and the body-first tools that bring you back when reasoning can't
• The truth about chronic shame: not shame about what you did, but the deeper shame about who you believe you are, where it came from, and how to begin dismantling it
• Why your nervous system never switches off: the science behind sympathetic dominance and what years of chronic stress actually do to your body
• The emotional reason you can't sleep: why the 3am spiral happens and the specific tools that work on the emotional brain at night, not just the behavioral one
• Why diets fail ADHD brains: the dopamine and interoception science behind your relationship with food, and a non-shame-based framework for working with it
• ADHD burnout at the identity level: not just the collapse of your systems, but the deeper question of who you are when you can no longer perform
• The mask, and what's underneath it: how you learned to suppress your authentic self to survive environments that weren't built for you, and how to begin taking it off safely
• The grief of late diagnosis: what changes when you finally have the right framework, and how to rebuild your sense of self on more accurate foundations
• A personalized regulation toolkit: evidence-based, body-first tools for calming a nervous system that productivity advice was never going to reach

The years of self-blame, misunderstanding, and carrying an emotional load no one helped you explain were written without the right information. You are a person with a specific kind of nervous system that has been waiting for this framework and the capacity for connection, creativity, and joy that comes with it is just as real as everything that has been hard.
