With the Asian leg of his 'Close Encounters' tour being canceled on account of the British singer's poor health, it seems that Robbie is suffering from something more than just excessive tiredness. As sources close to him told the British press, the star is also depressed and he is being treated against it in London.

Williams is no stranger to the condition, considering he went through it once before, as a consequence of abusing drugs and prescription medication in the mid-90s. As he told BBC, in a recent interview, his condition would get more aggravated every time he went on stage to perform.

'I could get up in front of 35,000 or 40,000 people and go, "Look at me, I'm ace!". Then, as soon as I got off the stage, I'd get in the tour coach and go back to my bedroom and pull the duvet over my eyes'. This time, though, he insists things are not as serious as the first time around but, still, he wants to prevent the situation from getting worse.

'I'm okay. I'm exhausted and haven't been home for ten months because of my tour and promoting my album. It's all got too much for me and I have been told to rest for two weeks. My South American tour is coming up and I want to be ready for that', Robbie told his friends and managers.

The dates for the South American gigs are set at the end of the month and the tour will round up in December in Australia. After that, Williams is said to take a long break from the music industry and, meanwhile, ponder whether he ever wants to sing again or not.
