Hello, nervous newbie here. I think she sounds like Ann Widdecombe! Very wobbly and nasal.
I too was a long-term Jack fan, all the way back from Hunger Hurts via that never-ending shenanigans with the kickstarter book. I think she is damaged beyond repair, sadly. Self-sabotages the good stuff, can only operate in chaos.
Does anyone else remember her 'I threw up before Question Time' nonsense ? 'You can still see bits of prawn in my hair'? That was about six years ago and she is STILL terrible and ill at ease on TV.
Anyway, I've been around for so long I'm bored of the broken engagements/disordered eating and body issues/nervous breakdowns/train pile-on tweets... I've seen the light. Tomorrow I'm BUSY taking her books to the charity shop (if they'll have them)!
Oh, and by the way I agree that she's tried EVERYTHING. ALWAYS. But never says 'what a great idea, I'll give it a go' or 'Never heard of that, thanks!' So ungrateful.
