Speaking on the Verified Views podcast, Frankie spoke about being hospitalised in 2012 for depression.
She admitted that it was actually her hospitalisation was a "God send."
"I've always had anxiety and I think back when I was really suffering, people didn't know about anxiety and depression," she explained.
"I genuinely believe if that was me now maybe it wouldn't have escalated into me hospitalised when I was."
She went on:
"You can feel like it controls you and that's what had happened to me. I felt I had control over it at one point and all of sudden I didn't. For me, knowledge was the key to understand what's happening to your body physically when you're having a panic attack."
And now, years on from her hospitalisation, Frankie Bridge is an ambassador for Mind, a mental health charity.
"The fact that my depression is a chemical imbalance and I'm not just going crazy. To meet other people that are feeling the same and to all be on medication and it's not this big deal," she said on the podcast, which went live on Monday."
"I think when I came out of hospital I just felt like with the fans of The Saturdays at the time that they deserved to know because I felt like a lie for the last how many years pretending to be this person I thought everyone wanted me to be."
Brave of her to open up in such a way.
