So, most of us can walk, right? Its such a privilege which most of us don't even realise. Not our friend, Lucy. At 18, whist at university, Lucy was diagnosed with a spinal Arteriovenous Malformation (AVM) - a rare condition that left her paralysed from the waist down. We're trying to help Lucy get to her total of £80,000 to buy a device that will let her walk again.

So, despite both Annabel and I being PETRIFIED of heights, we are abseiling down the Spinnaker Tower in Portsmouth - that's 560 feet or 170 metres. Argh! And Lucy is doing it, too. Please help us help Lucy get to her total - she's already proved unstoppable and raised over £50,000 - let's help her get her 'robot legs'. Thank you all in advance. Charlotte and Annabel.

Here is Lucy's story, in her own words:

"I used to walk. At 18 I was just your average university student in my first term getting adjusted to my new student life. That was until I was diagnosed with a spinal Arteriovenous Malformation (AVM), a rare condition that meant I had an abnormal tangle of blood vessels on my spinal cord. After a lot of operations, it was removed but the damage had already been done. I was paralysed from the waist down. The doctors told me it was unlikely that I would ever walk again.

It was a traumatic time but I got on with my life. I completed my degree and a masters programme. I have a fulltime job and I have thrown myself into fundraising for other people like me. But, even though I have accepted my condition, I have never accepted this wheelchair or the idea that I will never walk again.

Last year, I found the ReWalk exoskeleton. I’d seen this kind of tech before but ReWalk seemed different. They offered me a trial session and 10 minutes in, I was crying like a baby. For the first time in 14 years, I was walking across a room towards my family and friends.

Understandably, access to this kind of expensive tech doesn’t exist on the NHS. However my civil servant salary doesn’t stretch to include the £80,000 needed to buy this incredible device. I have always prided myself on never asking for help but now I need it.

I want to go on walks with my family without them pushing me when the terrain gets tough. I want to go shopping with my friends and be able to see over the clothes rails. I want to just walk up the stairs at my parents house.

I will work for it. From now on, for however long it takes, I will be raising money through various activities. Any contribution you can make will be immeasurably appreciated. Whether that’s a share of my campaign on social media, spare time to help me fundraise or a donation, everything helps!

I'm going to track everything I'm doing on my social media channels so please follow me and send good thoughts to help me on my way - I'm definitely going to need them!

Thank you so so so much to everyone who has already helped me on this journey, I can't express just how much it means to me.

Love Lucy x"
