A female military medic has told ITV News how her struggle with post-traumatic stress disorder has left her terrified to leave the house alone.
Paul Davies reports.
At the end of this week, every senior member of the royal family will attend a ceremony to thank Britain's armed forces for their efforts in Afghanistan.
Services at St Paul's Cathedral and around the country will recognise the sacrifice of those who lost their lives, or suffered life changing injuries.
For a country that became accustomed to seeing its young men and women returning home in coffins, it will be tempting to think a line has been drawn under this costly conflict.
That, according to veterans and military charities, would be a huge mistake. Thousands of our servicemen and women will be paying a terrible price for the forseeable future.
Some of the deepest wounds are not visible.
ITV News spent the day with Flight Lieutenant Michelle Sanderson who has been forced to leave the RAF suffering from the stress condition PTSD. Her story is brutally honest.
The first female RAF paramedic to work on the Afghan frontline, she now finds it impossible to step outside the front door of her Wigan home most days. She wets the bed and has recurring nightmares, in which she regularly finds herself back in Afghanistan surrounded by the horrors she has witnessed.
Flt Lt Sanderson completed three tours of Afghanistan. During that time, she was routinely flown by helicopter into the heart of the fighting to care for military and civilian casualties.
It was after the third tour that the impact on her mental health became clear - and in September last year, she was given a medical discharge.
It is not only in her dreams that Michelle sees bloody images from her past.
Michelle wears oversize headphones when she visits the supermarket to shut out the noise, but it doesn't always work. She has considered suicide on more than one occasion, and now keeps a blog about her experience.
Since her discharge she says she has had to find her own help. All the RAF have offered, she claims , is counselling at Catterick. That would be a five hour round trip from her home, something she is not able to face.
While she lived up to the RAF's ethos and core values, she says, she does not believe the RAF has held up its end of the bargain.
Michelle's mother Carole Johnston goes further, saying her daughter has been let down by the military who are not living up to the Covenant that promises to support the men and women who serve.
The MoD said it would not comment on individual cases, but said they take the issue very seriously and improvements continue to be made in caring for the mental health of the armed forces.
ITV News, however, has seen a letter from one of Michelle Sanderson's senior officers in the RAF.
In it, it is acknowledged that there are still problems in dealing with unseen mental injuries, and that vulnerable ex servicemen and women are still slipping through the net.
