Kuala Lumpur, Malaysia (CNN) -- Cheng Li Ping is afraid to tell her sons their father might never come home. "My heart can't handle it. I don't want to hurt my children," the Chinese woman told CNN Wednesday as she waited in Kuala Lumpur for evidence about what happened to her husband and the 238 others who were aboard Malaysia Airlines Flight 370. Cheng says she cannot bring herself to accept that her husband is dead, even after authorities announced there were no survivors. "I can't trust the Malaysian government. I can't work now because all I can think about is my husband and my children," she told CNN's Sara Sidner in Kuala Lumpur. "I don't have strength. ... My head is a mess."
