The phone-in addressed issues of anxiety and depression, and those who felt they could not cope.
A woman rang in and, under the false name of 'Rachel', she told Emma, Ruth and Eamonn: "I'm a single mum trying to run my own business.
"I’ve been through a lot. Everyone is very much 'you’re so strong and amazing' but actually deep down I’m completely falling apart and some days I don't know what to do.
"I have been happy. I’ve grown up with this feeling I’m not good enough. I feel people are talking negatively about me all the time and don’t like me. Even though I know I’m a really nice person."
She explained that she had tried CBT (Cognitive Behavioural Therapy) and had been put on a six-month waiting list for NHS counselling in her local area.
As Rachel began to cry, Emma suggested that she go back to her GP or A&E to demand help, especially if she was finding it difficult to carry on.
Ruth pleaded for her to stay on the line to talk to the show's in-house counsellor.
We're going to pass you now, because you're so upset, to Penny our counsellor. So please don't put the phone down.
She said: "We're going to pass you now, because you're so upset, to Penny our counsellor. So please don't put the phone down.
"But as Emma said, you've made the first step by making this call today.
"We're going to get you some help today. We're going to help you."
It wasn't long until viewers took to Twitter to lend their support to Rachel.
"Watching the phone-in on #ThisMorning. It must have been so hard for Rachel to make that call just then. So glad she's receiving support. Please consider extending this phone-in topic the entire week," one wrote.
Another said: "#ThisMorning heartbreaking to hear. I totally suffering from it myself."
Finally, a third wrote: "'Rachel' has broken my heart."
