Simon Cowell isn't always happy

Simon Cowell has a tendency to get depressed.

The X Factor judge, 49, struggles to control his feelings.

‘I get very dark moods for no reason,' says Simon.

'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.'

Simon realises his mood swings are caused by deep emotions.

If I went to see a psychiatrist, it would be a long session,’ he tells the Weekend. '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.'
