Stephanie has been open about her emotional struggles after retirement from professional swimming. 

'Everyone is searching for some purpose in life and 'what am I here for?' I think because I didn't have that, it then brought about [questions of], 'Who am I? What do I value? What do I stand for?'' she said.

She struggled to work out her purpose in life because until that point she had been focused solely on her sporting career.

'I realised how much of my identity was wrapped up in swimming but also the version of me as this successful swimmer, achiever and all the external gratifications, which everybody loves and needs aspects of, but I realised how low my self-worth was just as a person without any of those external things.'
