SUSAN Boyle's family today said the singing sensation will "bounce back" after being admitted to the Priory clinic suffering from exhaustion.
Her brother Gerry Boyle said the Britain's Got Talent runner-up is missing her home in West Lothian – and her cat Pebbles.
And Mr Boyle, from Musselburgh, believes his sister will soon be back on her feet ready to start her new career.
He spoke to his sister last night shortly before she was admitted to the Priory.
The 48-year-old spinster was taken to the private clinic last night after show staff contacted police to say she was acting strangely at her London hotel.
Mr Boyle will find out today how his sister's recovery is going. But he said:
"She is a bit tired and maybe even a wee bit homesick.
"When I spoke to her yesterday she was asking about her cat.
"It's going to take a wee while for her to get her head round all this because she just comes from a wee village in Blackburn.
"First and foremost we have to make sure she is happy, and she is – she wouldn't change all this for the world.
"It would be nice to get her back home for a couple of days.
"But she will bounce back – we know our Susan."
Mr Boyle added: "This is the start of Susan's international career, now that the talent show is finished. She is not interested in money, she's not a material person, but what she is interested in is working with her idols and I'm sure Mr Cowell will have a few people lined up.
"I was absolutely delighted with the result on Saturday.
"In my opinion, it's not about winning the competition, it's about where your career goes afterwards."
Susan was reportedly taken by ambulance to the Priory in Southgate, north London, escorted by police.
A Scotland Yard spokeswoman said: "Police were called at approximately 6pm to a central London hotel to doctors assessing a woman under the Mental Health Act.
"The woman was taken voluntarily by ambulance to a clinic. At the request of doctors, police accompanied the ambulance."
Television company talkbackThames released a statement offering her "ongoing support" amid newspaper reports that she had run amok backstage after her loss, shouting: "I hate this show."
She also allegedly threw water over a floor manager who tried to calm her down.
TalkbackThames said Susan was "exhausted and emotionally drained" after Saturday's show.
The company said: "She has been seen by her private GP who supports her decision to take a few days out for rest and recovery. We offer her our ongoing support and wish her a speedy recovery."
The 52-bedroom Priory specialises in the treatment of mental health problems.
Diversity took 24.9 per cent of the public vote in the final, above Boyle's 20.2 per cent share. The contestant in third place, saxophonist Julian Smith, gained 16.4 per cent of the vote.
Just under four million people voted, ITV said.
The Prime Minister added his best wishes for Susan Boyle. Speaking on GMTV today he said: "I hope Susan Boyle is OK because she is a really, really nice person.
"I spoke to Simon Cowell last night and Piers Morgan and wanted to be sure that she was OK.
She has made the whole of Blackburn unbelievably proud
"SHE'S still a winner!" That was Blackburn's battle cry after Susan Boyle's Britain's Got Talent dream was shattered by dance group Diversity.
The hopes of the small West Lothian community were dashed when the 48-year-old spinster was pipped at the winning post within touching distance of 100,000 and an appearance in front of the Queen on this year's Royal Variety Performance.
But judge Simon Cowell is still expected to offer her a record deal, and she is predicted to earn up to 8 million in the United States. She has already been approached to appear in an episode of the hit American TV series Ugly Betty.
Best pal Doreen Boyle, who spoke to Susan after her performance, said she was fine and took the result in her stride.
Ms Boyle, who is no relation, said: "She has made Blackburn unbelievably proud.
"Her future has not ended with this result. During all of this she did a 'beat the bully' campaign and that she has inspired so many young people."
Susan, and Blackburn, have been overwhelmed by the media interest since she first appeared on TV at her Glasgow audition in March. Camera crews from all over the world including the BBC, CNN, French, Japanese and Brazilian news teams flocked to record Blackburn in its moment in the spotlight.
Ukranian composer Mark Shamrakov, who travelled from his home in New York, to stay in Blackburn said the singer epitomised the 'American Dream' during her seven-week journey.
He performed eight songs he wrote about her life with local musician Doog Molloy in Blackburn Community Centre's sports hall.
"I am inspired by her very much," he said. "The songs I wrote are about her life from her family, to be being bullied and her church singing."
Saturday night started full of hope and excitement in the community centre and the mere mention of Susan Boyle on Britain's Got Talent sent the 300-strong crowd into raptures.
Youngsters and adults donned Susan Boyle t-shirts and face masks of Susan as they streamed into the hall.
When she was voted into the final three tensions rose to fever pitch as photographers and camera crews scrambled to capture every emotion.
But the bubble burst when Diversity's name was called out reducing many in the hall to tears.
Some locals said they felt Susan's over-exposure had cost her the result on the night.
Lifelong friend Angie Uttley, 49, said: "For the talent she has and what she's been through – to sing like that was amazing. She's a winner in our eyes, not a loser."
