Susan Boyle about her "most frightening experience"
The Scottish singing sensation was treated at The Priory clinic after failing to win TV talent show `Britain`s Got Talent` in 2009 and admits she felt isolated at the London facility.
She explained: "I was exhausted, I needed somewhere to go to recuperate - everybody knows that I went to The Priory.
"It was a bit of a scare, a scary time for me, being in a place like that. Although very therapeutic for some people, for people like me it was very scary.
"I thought, `I`ve nobody here I know, where`s my family? Where`s my friends? Do I have anybody left?` I wasn`t allowed to see a television, or make a phone call. `Where was everybody?` I just felt as though I`d been dumped, it was probably the most frightening experience I`d been through.
"I felt that the dream was over. A bit of a nightmare, but, a turning point. For two days I was thinking about myself, what my position was, was I stable? I knew I was, I was just tired."
The `Wild Horses` singer also admitted she has a terrible temper, likening herself to giant green comic book character the Incredible Hulk.
She added in an interview with Piers Morgan: "I have got a temper, I`m like the Incredible Hulk!
"It is a defence mechanism it was my way of dealing with a whole load of tension, I was channelling it into the wrong things. I was letting off fire at everybody and I really shouldn`t have been doing that.
"I think most of the time I was tired. I`ve learned to control that now."
The full interview was aired on `Piers Morgan`s Life Stories` in the UK on 06.11.10 on ITV1.
