The son of Sarah Wellgreen has written a heartfelt letter to his missing mum on his birthday.

Lewis Burdett, who turns 23 today, wished for the 'nightmare to end' in a social media post, saying he didn't think his time with the mother-of-five "would end so soon".

Sarah Wellgreen, 47, was last seen in the Bazes Shaw area of New Ash Green on Tuesday, October 9.

Eldest son Lewis posted: "Dear Mum, I wanted to write to you today, it’s my birthday...but you know that.

"I’m trying to carry on and be strong but days like this really hit me. I just wish you were here.

"I keep looking at my phone waiting for you to ring or message even though I know you cant and you cant be with me.

"I’m finding it hard not being able to talk to you, to tell you our news, what were all doing. I even pick my phone up without thinking to ask you something.

"I will love you forever mum." - Sarah's son Lewis

"I know I was lucky having you for so many years but I just didn’t think it would end so soon.

"So when it’s quiet I just sit and have a cup of tea and a chat, I know you can here me.

"I will Love you forever Mum. I’m going to share this letter with all the people helping to find you. So many people care about you and your in thier thoughts and that helps me know we’re not alone.

"I just wish this nightmare would end. Love Lewis."

The beautician has not been in contact with her family, including missing the birthday of one of her younger children, and her phone has still not been found.

Former partner Ben Lacomba, 38, was charged with the murder of Miss Wellgreen.

He denied the charge at Maidstone Crown Court earlier this month.

Lacomba will face trial on June 18.
