The bubbly TV host was treated with Neuro-Linguistic Programming, a technique which helps patients look at how they address stressful situations.
When asked about what brought on her anxiety, 33-year-old Caroline told the Daily Mirror: "It was all manner of things which just built up…
"Work stresses, life stresses, family stresses and relationship stresses.Talking to someone just helps as a problem shared is a problem halved.
"I loved it and to be honest it got me through quite a lot."
Caroline famously dated One Direction star Harry Styles from October 2011 to February last year, while he was 17. Their relationship attracted much attention, largely because of the 14-year age gap between them.
Caroline is over the split and says she has a much more positive outlook on life since undergoing therapy.
"You have your down days and your up days so something like NLP definitely helps. I'm very happy now," she says.
