Struck down with cancer, the 29-year-old was told the devastating news on Monday that there is nothing medics can do.
Her health has deteriorated so quickly that she is now in the Marie Curie Hospice in Elswick, Newcastle, where family and friends are saying their emotional goodbyes.
And, as she puts forward her funeral plan reflecting her vibrant personality, she is having to make arrangements for her Down’s Syndrome son Bobby to be cared for.
Sammi, of North Shields, who has five-year-old Bobby and 13-year-old Kai, who lives with his dad, is relying on her mum Denise, 51, to move into her house and look after Bobby.
But selfless Sammi is making sure Bobby’s birthday on December 19 and Christmas will be made special when she’s not there.
“She is so selfless, even though she knows she has days to live, she is making sure everyone else knows what needs doing and making plans for Bobby,” said sister Kelle, 32.
“Her friend Patricia Thomas set up a fund to raise money for her funeral but Sammi says she wants it to also be for her boys and to make Christmas and Bobby’s birthday on December 19 special.
“It’s heartbreaking to see her cuddle Bobby, knowing she’s not got long.
“Even my two-year-old daughter Brooke went to see her and said ‘are you going to be an angel like nanna?’. It’s devastating.”
