Surgery in Barcelona for my disease in my spine

Hi everyone I need help raising £16,700 for operation in Barcelona i sent full spine mri to them & they have picked up i have a issue with my filum terminale in the spine which no one else could pick up after all these years of wasting time, which acts like an anchor to your spinal cord at the bottom of your spine which it getting pulled in my spine from this issue i have which is not meant to happen in your body. I’m struggling to walk, can’t do basically anything from this issue right now, i might end up in a wheelchair without the operation so If i don’t get the surgery soon i could have potential permanent damage that’s unreversiable so please help me out as much as possible, I tried seeing if my family could help but they haven’t got the funds to do it so they told me to restart my page again. I’ve been physically ill for 3 years lost a tone of weight in that time & getting worse as it’s progressing, used to play rugby & was enjoying my life. From the imaging they want to do the operation on me so please contribute as much as possible please, all contributions will be super appreciated so I can try & attempt to get my life back on track like it was prior
