Rejection sensitive dysphoria

Rejection sensitive dysphoria (RSD) is a condition associated with what are deemed 'extreme' reactions to perceived or actual rejection.

Primarily associated with ADHD, there is research suggesting links to autism.

It manifests after traumatic experiences (shaming, isolation, abandonment) done (often subconsciously) by people around the individual. RSD can contribute to feelings of worthlessness, social anxiety, and over-sensitivity, and, in general, makes it hard to create new connections.

It can have a significant impact on the mental health of those experiencing it.
