Cher (born Cherilyn Sarkisian) is a world-famous US singer and actress.
"In the early 1990s, she contracted the Epstein-Barr virus and developed chronic fatigue syndrome (CFS), which left her too exhausted to sustain her music and film careers." Cher was diagnosed with CEBV (Chronic Epstein-Barr Virus) and reputedly went to Brussels, Belgium for treatment and recovered.
When asked in a BBC interview if she thought the illness was psychosomatic, Cher replied, “My experience was that it was really a physical illness — but it does make you depressed as well ... Boy, it was devastating for me.”"
