Regardless of her chances of winning all participants should be treated with a level of respect. Now I'm sure the reality of what happened on the day is somewhere in the middle but over the past few years it has become clear that reality shows need to do more to offer mental health support to participants. Zoe mentions she tried to take her own life. We've seen that happen with contestants on Love Island.Plus, she would never have got to the live shows anyway let alone won the competition.
If the show isn't going to provide them with that support I can understand why she feels having an environment where people can share their experiences would be helpful. I don't think they'll be able to do anything out of it (I'm sure the X Factor contracts are water tight and frankly I'm surprised she's as open as she is with her claims), but at least they'll be able to support one another.
