“I lost everyone, you know.

Ive lost my parents.

What I said about the material things Ive got, everything just meant nothing at that point.

Cowell was “desperately unhappy,” he recalled.

“I wasnt particularly enjoying my work and I just thought, you know what?

I was very successful but I wasnt happy, I really, really wasnt happy.

“It changed everything in my life.

It made me happy again,” Cowell said.

Even to the point that I almost cant remember everything from that period.”

“Id put on a ton of weight, I was eating junk.
