It’s now about buying as much time as we can for Brett

and he wants to raise awareness of this awful illness which can creep up on people.

“So becoming an ambassador for The Brain Tumour Charity was something I had to do for him and the people we may be able to help.

“I think about Brett’s prognosis every minute of the day. As a family we have vowed to live in the moment for Brett and for ourselves to get the very most out of the time we all have together with him. Fear touches everything now. It overshadows everything we do.

“I don’t allow myself to look too far into the future – it’s too frightening, so I don’t let my mind go there. He’s selfless and all he worries about is the impact on his family – that’s when he breaks down.”

Sherrie has now enlisted the help of a special medical company called Oncologica, which runs a DNA service and, after testing Brett’s tumour, has come up specifics drugs which may help him live longer. Sherrie said: “The NHS has been amazing, they saved Brett’s life, now it is all about buying him as much time as we can.

“I’ll do everything I can to get him the very best treatment and if I have to work 365 days a year so be it. I’ll do anything.”

Sherrie, who revealed her own breast cancer scare in 2015, is aiming to raise £50,000 for The Brain Tumour Charity by offering a lunch date with herself on the good causes website Rafful – as well as an overnight stay in a London hotel for the winner.

Meanwhile her family is doing all it can to support Brett, who said his little sister and the rest of his family have been “amazing”. He said: “Sherrie and I are incredibly close and I confide my feelings and fears in her – I can tell her anything.

Fabulous

“We’re bound together by love and humour.

“Sherrie will always be my Shez – I’ve always called her that and always will. People think there must be ‘ side’ to her because she’s an actress but she’s the same lovely, down-toearth girl she’s always been.

“She is such a loving person with a fabulous big heart and would do anything to help anyone, especially her big brother. I’ve always told my family I love them but now I tell them I love them every time I see them and hug them closer.

“I’m grateful I’ve had such a rich, full life right up to my 70s, and I feel blessed ed I’ve got such a l oving, ng, supportive family ily around me.

“Every one e of t hem is amazing. Chloe saved my life and Annie is my rock. I don’t t know what I’d do without her. I know now nothing about t brain tumours. When d doctors told ld me I had a glioblastoma I asked, ‘Is that serious?’

“The answer was, ‘It doesn’t get any worse.’ When I was told it was terminal I just couldn’t take it in. It feels like it’s a story being told about someone else.

“You’re in such a heightened state of emotion and shock that you can’t process it at first. You have to face your own mortality. This is what you’ve got and it’s going to kill you in 12- 18 months. I’m learning to accept it, one ste step at a time.

“I’m not scared or sad for myself but I am scared and sad f for my family – w what lies ahead of them and the grief they’ll face.

“We ’ r e all d doing our best to li live in the mo moment.

“I ha have everything I want or need – my family – and I just want to spend time with them. Now it’s about living the best life I can in the time I’ve got left.”
