Olivia Turner, 26, has been struggling with blood clots for years, with the thrombosis striking so badly at times that her leg has swollen three times its size.
While giving birth to her first child at the age of 20, Olivia was placed on emergency blood thinning to try and stop the blood clots reaching her heart and lungs. She nearly died in the weeks after the labour.
Just one month later after the birth of her youngest child, the clots did reach her lungs, stopping her from seeing her newborn daughter for a week, and instead having to write goodbye letters to her loved ones in case she didn't survive.
Now, the clots have left Olivia with such intense scars, she can't walk her kids to school and can't make it out of bed some days to see them.
Olivia lives in West Derby with her daughters, Bella who is five, and three-year-old Phoebe.
She wanted to raise awareness about thrombosis on World Thrombosis Day, 12th October, to encourage people to get tested for the disease.
Olivia says to young people who have thrombosis in the family: 'People think they're invincible but one thing I've learnt is that you're not, no matter how old you are.' She urges everyone with a family history of the disease to get tested.
Thrombosis is hereditary and is passed down the female line, so Olivia's daughters have half a chance of getting it.
The condition has seriously affected Olivia's ability to join in with everyday activities as a mum.
'Some days I feel like I've failed as a mum, or that I'm not a proper mum because I try and do as much as I can, like I bake cakes with them, but there's so much I can't do with them,' she told the Liverpool Echo.
'When I was pregnant I thought I'm going to be a mum that does everything but I just couldn't do it. At night I was awake when my baby was crying but I couldn't get to her. It was the worst experience ever.'
Olivia has always dreamed of taking her kids to Disneyland, but she doesn't think she'll ever be able to due to her thrombosis.
She studied at St John Bosco Arts College, and became a case support worker with Merseyside police aged 17, but was forced to give up her job when she was 21 because she was too ill.
Olivia is worried about the impact the disease has on her daughters.
'Sometimes when I come down the stairs and I'm in a lot of pain, my daughter will hold my hand, and she's only five. That breaks my heart. She shouldn't have to be doing that,' she said.
'I know that if something does happen to me everyone will know how I feel about them because I have written them letters. My kids are only five and three, they will remember me but I want them to have something from me.'
The mum has tried to get her thrombosis treated, but it hasn't worked so far.
'They've tried lots of different treatments and I don't have many options left.'
'I talk to my husband and say if something happens I want this or that for the kids. A lot of people, like my mum, find it so painful they say "I don't want to know, it's not going to happen".
'Hopefully it won't, but I need to know that I've spoken to someone about it and that they know what my wishes are for my girls.
'I need to do it because it makes me feel better, I need to know that things are in place.'
