Storminateacup I disagree - MH has a huge part to play in behaviour when not diagnosed is seen as 'attention seeking' or 'extreme'
He had a late diagnosis of ADHD - my nephew has ADHD and took drugs and behaved in a horrible way sometimes - now he's on medication he's a much calmer person.
I think that Robbie is a much calmer person now and has come across really well on the X factor, showing lots of empathy towards contestants and Ada has absolutely been his rock.
There IS an excuse to behave how we wouldn't normally if you have an undiagnosed mental health condition.
