"If I went to a psychiatrist, it would be a long session. I've always thought that I do have a number of issues that probably need dealing with, because I am quite odd in some ways. I get very dark moods for no reason. Nothing in particular brings it on. You can be having the best time of your life and yet you're utterly and totally miserable. I get very anti-social, depressed and irritable with people. I don't have time for them. I can't make phone calls and stuff. I just sit on my own for days," The Daily Star quoted Cowell, as saying.
Despite having everything, Cowell says he has a tendency to torture himself. "I'm not sitting in a darkened room rocking. Things might have gone really well and then I torture myself. I cannot believe it. I have to find something to make me miserable. I get to points in my life where I sometimes think I'm never going to be happy. Someone said to me recently, 'You're like a human buffet table. Everyone comes and takes something from you and, at the end, there's nothing left," Cowell added.
