Robbie Williams has admitted that he cannot do without anti-depressants as it 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.
