"What is Rejection Sensitive Dysphoria?
Rejection Sensitive Dysphoria, or RSD for short, is a common issue experienced by Neurodivergent (ND) people. It is thought to be caused by increased difficulty in regulating our emotions, which leads to an incredibly heightened experience of rejection.
Put simply, it is an increased sensitivity to rejection (as the name implies), and the rejection does not have to be real. It can be imagined or feared. RSD can be incredibly intense, and we can feel it to the core of our being as intense physical pain, discomfort, and sensory overwhelm. It can be almost impossible to reign in these sensations when an intense episode is triggered. For me, it’s chest pain ache and discomfort, and tightness, and not being able to breathe, like a knife has been stuck into my chest. It can come on so rapidly, it can consume me before I can even consciously articulate it."
