She told the paper: "Every day is a nightmare for me now. "I feel completely helpless. Helpless, and also, sorry to use this word, but I feel useless. Because I want to go out there, to do something to look for him, search for him, anything. "But I can’t", she said of needing to remain at home in case he makes contact. Richard Okorogheye.
