'As many of you know, this is a cause very close to my heart. Their charity slogan is 'positively changing what it means to have ADHD in the UK' – and that just sums up my own mission as someone diagnosed with ADHD not too long ago.
'Their 5 goals as a charity are - Information, Support, Research, Advocacy, and Awareness – and I hope to use my own platform and audience to help with all of these.
'Changing perceptions of those with ADHD, and encouraging conversation around this topic is and will continue to be a huge and central part of my life. This is what I want my legacy to be, above anything else.
'Since I left the jungle, I've met so many children and adults who have come up to me, or contacted me to say I've helped change their minds on how they view ADHD.
'I want to reach as many people as I possibly can, especially young people, and show there is such magic in being neurodiverse.
'Yes there are some very real challenges along the way, but with the right support, it can be a superpower, it can be a blessing and we can achieve all of our dreams.
'Thank you @ADHDUK.CO.UK for all the work you do for people like me, I am so pleased to be on the team!'

While speaking with campmates Marvin Humes and Josie Gibson, the TV personality said he is 'not ashamed' of his diagnosis
While speaking with campmates Marvin Humes and Josie Gibson, the TV personality admitted he has 'terrible time keeping' and 'gets quite selfish' with friends and Love Island girlfriend Zara McDermott.
Marvin asked Sam: 'How old were you when you were diagnosed with it?'
Sam replied: 'Last year, mate. There's loads of people who are actually like of a certain age who get diagnosed way later.
'When the low bits happen it goes low. But then the highs are really high. My girlfriend Zara is so steady and it's so good for me. When she's going steady I'm going like that.
He continued: 'My timekeeping is terrible. I get quite selfish, not just with her, with everyone, my mates or whatever.
'My listening to Zara… I'm just finding myself staring off at something completely different. You sort of feel like you're a bit of a k*** sometimes.'
Josie said: 'But you would not be Sam without it.'
Marvin added: 'I would just always say you've got loads of energy. Your energy is crazy bro and it's what makes you great.'
Sam said: 'Weird no one spotted it beforehand at school, but if you look at all of my report cards, every single one says the same, it says: "Likeable enough guy, but lacks focus".
'It's staring at you in the face. If I'd known as a kid, not much would have changed, but how you feel about yourself probably changes.

Sam went on to say he would like to become a dad one day but needs to 'get a handle' on his ADHD, he said: 'I want to be a dad at some point. We've got to get a handle on it. You've got to look after a child'
Marvin, who shares three children, Alaia-Mai, 10, and Valentina Raine, six, and three-year-old son Blake, with wife Rochelle Humes, said: 'You would be the most incredible dad'
'I remember crying into my textbook because I couldn't understand the words going into my head. You want to do good. You don't want to be mischievous or anything like that.'

JLS singer Marvin, who shares three children, Alaia-Mai, 10, and Valentina Raine, six, and three-year-old son Blake, with wife Rochelle Humes, said: 'You would be the most incredible dad.'
Sam said: 'What you're doing now, sitting down, having an honest conversation, being able to listen, advise…'
Marvin advised: 'Trust me, all my kids care about is giving them attention, being with them in the moment, loving them, cuddling them, they just want to have all of you and to be as fun as possible and feel loved.'
Marvin added: 'I can't imagine doing this without you being here and you being as much fun as what we've had.'
Josie agreed: 'Yeah, no way!'
Later, the radio presenter admitted in the Bush Telegraph that he felt like he 'sucked at everything' before he was diagnosed.
He said: 'I'm not ashamed of having ADHD in any way. But I know that I would have felt better about myself at school if I'd been diagnosed with it at a younger age. I really was just like, "I just suck at everything".
'Big Marv, he's a really thoughtful bloke and such a great listener. He's just a really good guy.'
