Piers' comments were criticised by mental health charity Mind, who said in a tweet it was “disappointed and concerned” by his comments.
The organisation added: "It’s vital that, when people reach out for support or share their experiences of ill mental health, they are treated with dignity, respect and empathy."

The pair had been discussing Harry and Meghan's interview with Oprah, when Alex explained: "I understand that you don't like Meghan Markle, you've made it so clear a number of times on this programme.
"And I understand that you've got a personal relationship with Meghan Markle, or had one before she cut you off, she's entitled to cut you off if she wants to. Has she said anything about you since then? I don't think she has, but you continue to trash her."

Following this statement, Piers abruptly stood up and walked off, saying: "I'm done with this, sorry," as Alex told him: "You know what, that's pathetic...
"This is diabolical behaviour. I'm sorry but Piers spouts off on a regular basis and we all have to sit here and listen. [Yesterday's episode] was incredibly hard to watch."

On Tuesday evening, the Queen broke her silence following the airing of Harry and Meghan’s interview on ITV on Monday night.
In a statement released by Buckingham Palace on behalf of the monarch, 94, it said: "The whole family is saddened to learn the full extent of how challenging the last few years have been for Harry and Meghan.
"The issues raised, particularly that of race, are concerning. While some recollections may vary, they are taken very seriously and will be addressed by the family privately.
"Harry, Meghan and Archie will always be much loved family members."
