For the last four years, British singer Robbie Williams has been fighting a mystery illness.
The star worried his depression had came back when he was feeling sluggish but doctors later told Williams he was going through an unknown condition.
The singer has been receiving treatment to fight the illness since he was diagnosed earlier this year. Williams insisted that it “changed” his life. On British radio station Magic 105.4 FM, he stated, “I thought I was lethargic and depressed as a person. I thought that was my make-up. I found out a few months ago that I’d been ill, completely by mistake, and I don’t want to go into the whys and wherefores but what I had made you lethargic and made you depressed and I’d had it for years and not known and I’m on treatment for it. It’s changed my life.”
