Well, since they won’t let me post a link to it, I’ll just copy the description.
Quote from ADDitude page about RSD
“Rejection sensitive dysphoria (RSD) is an intense emotional response caused by the perception that you have disappointed others in your life and that, because of that disappointment, they have withdrawn their love, approval, or respect. The same painful reaction can occur when you fail or fall short of your rather high goals and expectations. RSD commonly occurs with ADHD, and causes extreme emotional pain that plagues both children and adults — even when no actual rejection has taken place.”
