The showbiz patriarch admits he feels guilty that a part of him is relieved that he is no longer constantly having to worry about the `Rehab` singer, who died last July following a drinking binge. He said: "In a way, subconsciously, it`s a relief that I don`t have to keep checking up on Amy. "I`m not going through pain every night, wondering if she is going to die, what she`s doing, or if she is in trouble. "There was a time in the midst of her drug addiction when she could have died on several occasions and I was always worried about her. "So, in a way, it`s a little bit of guilt - on my behalf - because I am able to sleep at night now." Mitch, 60, is still struggling to come to terms with Amy`s death and even still sends her text messages. He told Grazia magazine: "Sometimes I text her telling her to come home. But she`s never coming home and I`m going to have to deal with that for the rest of my life."
