Robbie Williams has confessed he is dependent on the medication that helps him cope with depression.

The British singer, who has had a history of alcohol and drug abuse, said he feels “suicidal” when he stops popping the pills.

“You get suicidal when you come off them (anti-depressants),” Contactmusic quoted him as saying.

“There’’s a buzzing, and weird things start happening. It’’s very scary,” the former Take That star added.

Williams ditched an addiction to painkillers and came out clean after checking into a rehabilitation centre in Arizona in 2007.
