Why Some People Are Afraid to Feel Joy

Cherophobia is the fear of happiness or showing joy, often driven by anxiety, guilt, or superstition about attracting bad luck. 

Though not an official diagnosis in the DSM-5, it can significantly affect quality of life and may overlap with anxiety or depressive disorders. 

Common signs include avoiding joyful activities and feeling anxious about positive experiences.
