Kadeena Cox says being at the World Para-Athletics Championships in Dubai, where she won a silver medal on Monday, triggered a relapse of her eating disorder.
The 28-year-old Briton, who won T38 400m silver on Monday, first spoke of what she calls her “disordered eating” in April, external, but told BBC Sport in October she was now in a “much better place”.
But Cox said she had been struggling having “so many eyes” on her in Dubai.
“It’s been a challenge,” she said.
“It’s been tricky trying to deal with managing my eating, having so many people around me and so many eyes on me, it’s pushed me to do more extreme things which is frustrating for me.
“A few bad habits have snuck back in that I thought I had got rid of. I’m annoyed with myself, it’s hard not to think, ‘if I had done this or not done this, would I have won?'”
