For many people who spend their lives online, confidence looks effortless.

But fitness influencer and content creator Caitlin Hood has revealed that behind the smiles and bubbly personality her followers know today was a young woman fighting a private battle with anxiety.

Appearing on the "She's Gutsy Podcast", Hood opened up about how anxiety once had such a grip on her life that it dictated how she interacted with people and even how she saw herself.
