Watch: Kerry Katona found challenge of Celebrity SAS therapeutic
The 40-year-old former Atomic Kitten singer competed in the new series of the Channel 4 reality show alongside stars including Strictly Come Dancing pro Ore Aduba, X Factor winner Alexandra Burke, Olympic rower James Cracknell and TV presenter Ulrika Jonsson.
Katona told The Mirror: “Whether it was physical or when you are being spoken to or shouted at, for me, that was therapy. I think I got so much closure from doing that show for my own personal life.
“It really opened my eyes up to who I am, and the worth of who I am and about not having to prove anything to anybody.
“So for me, it was huge therapy and massive closure."
The show sees the celebrities put through a gruelling military training regime, as well as being subjected to harsh interrogation to see if they have what it takes to be a Special Air Service army officer.
Katona said: “I have bipolar, my moods change with the weather, so when you are in an environment that is just so f***ing miserable, it’s really hard to get your mindset as, ‘Right let’s get up and put these wet clothes back on’.”
Also taking part in the upcoming series are reality TV star Vicky Pattison, former Loose Women panellist Saira Khan, X Factor contestant Jake Quickenden, ex Love Islander Wes Nelson, footballer Kieron Dyer, Welsh Paralympic athlete Aled Davies and BMX champion Shanaze Reade.
