A “fantastic” and “lovely” young mum is believed to have taken her own life after she started treatment for a mental health condition.
A friend of Casey Thornhill, from Beighton, Sheffield, said she had spent years seeking help for her poor mental health before she was diagnosed with borderline personality disorder.
Family friend Rachel Jackson said the 21-year-old was in ‘a really good place’ before she died on December 16.
Casey leaves behind her three-year-old son Noah, a boyfriend and a loving family.
Her heartbroken mum Julia has said that she wants to raise awareness of the illness so that others suffering from it can get help.
Some of the symptoms of the illness include emotional instability, disturbed patterns of thinking or perception, impulsive behaviour and intense but unstable relationships with others.
Rachel, who has known Casey since she was around eight-years-old as she lived opposite their family home, has set up a Go Fund Me page to raise money for Noah.
So far almost £17,000 has poured in from generous donors.
Rachel said: “I lived opposite her mum so watched Casey grow up. She had troubles from being a teenager.
“Her mum Julia fought to get her the right help and Casey did too once she became an adult.
“Casey was eventually diagnosed with BPD, borderline personality disorder, and since then she has been fighting for the right treatment.
“She had just started treatment before her death, but obviously it was just too late for her.
“At the time she was in a really good place and recently had her nails done and bought Christmas pjs for the family.
“But one thing that people don’t realise with BPD is that changes can happen really quickly.”
Paying tribute to her childhood friend, she continued: “Casey was a lovely person, vibrant and full of life. She had some really good friends and most of all she was a fantastic mum.
“There’s not much you can do in this situation so we thought that we would set up a fundraiser that will help Noah in the future.
“We also wanted to help raise understanding of the illness. Casey wanted help, she knew she was ill and she just wanted to be OK for Noah.
“But the illness can make things happen really quickly and suddenly.
“It really was a tragic ending.”
