Trinny, now 61, shot to fame in 2001 hosting the What Not To Wear show on the BBC.
But in the December issue of Women’s Health, she said: “I felt relieved to be alive.
“I had six friends die in my first year of recovery.
“It’s difficult looking back.
“If I hadn’t gone through it, I might not be where I am today.
“We only learn when we’re challenged.”
Trinny, who has a daughter from her marriage to musician Jonathan Elichaoff, also said she was happy being single.
She added: “Being with my daughter, travelling and having dinner with people who fascinate me.
“If, along the way, I meet someone, great, but my priority isn’t, ‘I have to date’.
“When friends ask, ‘Have you met someone yet?’. I go, ‘No, and I don’t really give a s**t. By the way, how’s your boring husband?’.”
