Gerry Boyle told GMTV Friday that his sister had been released from the London clinic. She was admitted Sunday, after coming in second place in the "Britain's Got Talent" television show.
Gerry Boyle says his sister suffered from an anxiety attack but now seems "a lot more like herself."
In eight weeks, Boyle went from the quiet life of a church volunteer in a small town in Scotland to global fame.
