Stephen Fry and Carol Vorderman have been taking part in an experiment to grow portraits using their own bacteria.
Writing for ITV News, Alastair Campbell asks why people find it so hard to see mental illness for what it really is - an illness.
Mental health problems can take many forms and can affect anyone at any time. Some of the possible early signs and where to find help.
Paul Farmer, the chief executive of mental health charity MIND, says Stephen Fry is helping to "sweep away the stigma surrounding mental health".
He said: "Stephen Fry, our president, has been extremely open and honest about his own mental health and the depths of despair he has experienced, and we know just from the response we've had in the last 24 hours how important that is to thousands of people who now feel that they're not alone."
There are around 6,000 people who take their own lives in this country every year.

The actor and comedian Stephen Fry has shocked fans by admitting that he tried to commit suicide last year while filming overseas.
Fry, who suffers from manic depression which causes his mood to swing between euphoria and deep depression, said he was only saved because his producer found him unconscious in a hotel room.
Fry said he decided to speak out because he believed his role as president of mental health charity Mind compelled him "not to be shy and [to be] forthcoming about ... the likelihood of death amongst people [with] certain mood disorders."
Speaking of manic depression, he said: "I have a condition which requires me to take medication so that I don't get either too hyper or too depressed to the point of suicide."
