Weighing 20.5 stone the 19-year-old from eastern Thailand has suffered painful school memories of bullies and a lifetime of loneliness.
“I used to feel like a freak, school children used to bully me and call me names,” she said.
"But since leaving school I’ve tried to feel more comfortable with who I am. I’ve got used to life on my own, but it’s hard.”
Malee’s mother, Ji, 40, did not realise Malee was ‘different’ until she was around nine-years-old when she began to grow much faster than her school friends.
“I took her to the doctor because I wanted to be sure there was nothing seriously wrong with her."
But Malee was diagnosed with a brain tumour, which was pressing on a nerve causing a hormone imbalance.
Malee has also lost the sight in her eyes as a result.
“I’ve been tall for as long as I can remember and taking medication is part of my daily life,” she said.
“But as I’ve got older my eye sight has got worse and it’s really difficult for me to get around.”
Malee needs an injection every three months to control the benign brain tumour and stop her from growing.
But it’s costing the family almost £2,000 a time.
"The injections have really helped to control her growth but they are expensive," said Ji.
"She is supposed to have an injection every three to six months, but we can't always afford them so we are not sure if she's still growing."
For the time being Malee's condition appears to be under control and her life has turned around.
She no longer attends school and is glad those days are behind her.
“All the kids used to call me names, the one I could never understand was ‘Dirty Malee’. They were always so nasty," she said.
“It would make me so sad. I was desperate to have some friends to play with but they all ignored me.
"Thankfully I had a good teacher who tried to help me and now I have nothing to do with them.”
Malee now spends all her time with her family, especially her three-year-old little sister, Daoruang.
She added: “I help my mother around the house and cook meals. Or I’ll cycle to see my aunt in the next village. I don’t do much.
“I’ve never had a boyfriend. I don’t think marriage is possible for someone like me, I’m just too different.”
But as Malee gets older she would love some more independence.
“My father gets very worried about me, he doesn’t let me go anywhere alone because sometimes I need help getting up, I’m pretty heavy," she said.
"But I’d love to be like any other 19 year old and live alone, build a life for myself and have fun but who knows what will happen.”
Malee was in The Guinness Book of World Records as the tallest girl in January, 2009. And not even the Brazilian Elisany Silva, 16, has knocked her off the spot as she only measures 6ft 9ins (206cm) tall.
