Susan Boyle has said her super-charged rocket drive to fame was like being hit by a "demolition ball."

The overnight success sensation has admitted that her sudden ride to fame was behind her high-profile meltdown after she lost the final of Britain's Got Talent.

"The impact, like a demolition ball. You know, and anyone who has that kind of impact - finds it really hard to get a head around it," Boyle told Meredith Vieira on the "Today" show.

"I've got to be honest here,' Boyle said.

"I guess I had to get my head around it, but through the - the guidance of a great team, and they are very good, I was able to see that in perspective and really turn that around a little."

Boyle's audition rendition of "I Dreamed a Dream," on "Britain's Got Talent," attracted 275 million hits on the Web and turned her into an international star.

"Being plucked from obscurity is a bit like, you know, going on a long journey," Boyle said.

"You don't know what's going to happen. You don't know how it's going to end. I don't want it to end."
