Hysteria, a term that was once used to describe a range of emotional and physical symptoms, is no longer recognized as a medical condition. However, in modern language, the term "suffering from hysteria" can be used to describe someone who is experiencing extreme emotions or behaving in an irrational or exaggerated manner. Some synonyms for this phrase include "in a frenzy," "beside oneself," "overwhelmed," "hysterical," "panicked," "frantic," and "out of control." While these terms may be used to describe someone who is experiencing strong emotions, it is important to remember that individuals who are suffering from mental health issues should be treated with compassion and understanding.
