The wife of nature conservationist Steve Irwin is struggling to cope with single parenthood since the death of her husband after a freak sting ray attack last year (SEP06). Terri Irwin expressed her anguish at Nickelodeon's 20th Annual Choice Awards in Los Angeles on Saturday (31MAR07). The mother-of-two tells, "It's extremely difficult. Part of me is still waiting for the day that he walks through the door. "We have so much footage of Steve and we watch it so it's like we almost get to see him every day. The kids and I have good days and bad, but you just deal with it as it comes."
