A teenager with a life-threatening lung condition was shocked to discover an aggressive note plastered to her car windscreen.

Yasmin Swift struggles to walk the length of a room and has a cocktail of drugs fed into her chest intravenously, but a disgruntled passer-by decided she was not entitled to her blue badge when she parked in Tenterden.

The 19-year-old found a note saying: "You are parked illegally. You are not disabled. I will inform authorities accordingly."

Yasmin has been off work for six months since doctors at St Thomas' Hospital in London told her that the explanation for her breathlessness, headaches and swelling on her legs was Idiopathic pulmonary arterial hypertension (IPAH).

Her rare condition can lead to fatal damage of the right side of her heart if left untreated and medics have told the hairdressing student that she may need a heart and lung transplant.

The ex-Homewood School pupil who lives in Willesborough, Ashford, was just starting to gain her independence after months of hospital visits and surgery and decided to visit friends in her former home town of Tenterden on Thursday.

She parked in a disabled space in Tenterden High Street, opposite Prezzo, only to return to her car and find the note written in capital letters underneath her windscreen wipers.

Yasmin, who wrote about her experience on Facebook and was inundated with messages of support, said: "I was shocked to find the note. People are ignorant and it's a cowardly thing to do.

"If the person who wrote the note had asked me about my disabled pass I would have told them, but it might have been a waste of breath.

"Maybe if they could have seen what I've been going through over the last few months they would think differently. People don't know you but they make judgements."

Yasmin has had to put her training at Ashford's Hair Academy on hold as she struggles to manage daily tasks with her debilitating condition.

Doctors hope the symptoms could be managed for up to eight years with tablets alone, but Yasmin needed more drastic intervention.

She now has the intravenous drip permanently attached to her chest, connected to a pump, which moves the drugs around her body but it is not a cure for her condition.

Yasmin's mum Mandy said: "Our lives have been devastated since Yasmin's diagnosis and quite frankly it's been hell. The incident with the note could set her back and it's just complete ignorance to write it.

"She's a beautiful girl inside and out and so positive and determined despite her illness."

Yasmin said: "I know I don't look disabled but I just want people to think twice before they write something like that."
