Country music star Shania Twain bares all in her new memoir, revealing that the end of her 14-year marriage caused her to lose her singing voice.

In the new book, titled ‘From This Moment On,’ Twain shares that her inability to express her feelings finally caught up with her and affected her ability to sing.

“I’m going to have to go through some very serious physiotherapy and recovery to be able to sing again,” Twain told ‘Canada AM’ co-hosts Beverly Thomson and Seamus O’Regan today.

It’s been three years since Twain, 45, ended her marriage to Robert Lange, 62. The split came after Twain learned Lange had fallen for her best friend and close confidante, Marie-Anne Thiebaud. That’s just plain awful.

“It wasn’t difficult to write this book. It was difficult to share it with the public,” said Twain. ”I’m sure I’m not the only one in the world who has gone through the things I’ve gone through. I know I’m not alone.”

In the memoir, Twain writes how she was “freezing cold all the time” and would take five hot baths a day just to warm up. Even then, Twain would “wear a winter coat” over her pajamas.

After she learned of the affair, Twain recounts how she felt chilled to the bone yet she was dripping in sweat for one long, dark, week. She writes that she was “forcing the pain out of my pores so I wouldn’t drown in it.”

Twain is no stranger to heartache, unfortunately. She grew up in Timmins, Ont., in a household rife with financial difficulties and arguments. Twain’s mother battled depression, but was the driving force behind Twain’s music career. ”In the more desperate times she pushed me because she needed it more than I did,” said Twain.

Twain eventually married Thiebaud’s ex-husband, Frederic, on January 1, 2011 in Puerto Rico. Kind of ironic, but I’m glad she found happiness.

Since she disappeared for such a long time, I’m glad she’s making her triumphant return in a stable state. Hopefully she’ll regain her voice and make more music – Canada misses her!
