Crippling agoraphobia left British singer Alison Moyet a prisoner in her own home. Moyet, 46, believes the debilitating condition was a result of overnight success with 80's pop group Yazoo. She says, "I never went out. For months and months I wouldn't even go into the garden. There were kids outside my door and I even hid in cupboards because there were people pressing their faces to my window."
