I remember watching the live shows of the X factor back when they won and it was very apparent, that she took the public criticism badly, I don't think she has fully recovered from that.
People are absolutely vile, it literally makes me sick when I see some of the things that people say.
She has such a huge following and loads of people who admire her, but like all things you can have 99% of people say positive things and you will always focus on the 1%.
I hope she has the right support and I hope this hiatus will do her good. I think people will want them to come back and be a strong, powerful girl group.
