Some common signs of Rejection Sensitive Dysphoria (RSD) include sudden emotional outbursts, low self-esteem, fear of failure, avoidance of social settings, high expectations for oneself, and persistent fear of being rejected or criticized. During an episode of RSD, the sensitive individual may feel overwhelmed with negative thoughts and emotions, experience physical pain, and have difficulty thinking rationally. Symptoms of RSD can sometimes resemble mental health conditions like depression, social phobia, bipolar disorder, borderline personality disorder, and post-traumatic stress disorder (PTSD). RSD is often associated with Attention Deficit Hyperactivity Disorder (ADHD), and it is more common in people with ADHD. However, RSD is not a formal diagnosis.
