ADHD & Rejection Sensitive Dysphoria: The Emotional Pain No One Explains
The Hidden 20%
Dr Shyamal's ADHD experience and caseload
Dr Shyamal describes his background, seeing thousands of adult ADHD assessments and work in prisons and courts.
In this episode, Ben sits down with Dr Shyamal Mashru, Consultant Psychiatrist and Medical Lead for Adult ADHD, for a clear and compassionate deep dive into Rejection Sensitive Dysphoria (RSD).
Often misunderstood or dismissed as being “too sensitive,” RSD is explored here as a real, neurological experience - one that can hijack rational thought, flood the body with emotional pain, and quietly shape relationships, work, and self-worth. Dr Shyamal explains what RSD is (and isn’t), how it shows up differently across people, and why ADHD brains may be especially vulnerable.
They unpack the science, the role of trauma and hormones, why RSD isn’t currently in the DSM, and what actually helps when rejection hits hard.
If rejection feels overwhelming, confusing, or deeply personal - this conversation offers clarity, relief, and language for what you may have been carrying alone.
