PIP Tribunal Advice

Hello, i’ve recently been fighting pip for quite some time now and finally got a call back yesterday refusing my enhanced mobility. I already claim standard for both but have recently seeked legal advice from NBAC who have helped me build a profile to aid me in my appeal. I’m a young adult (24) who has suffered from SEVERE depression and anxiety from since i can remember. I have severe agoraphobia from being randomly attacked multiple times and recently found out i have a very rare condition which included multiple hernias located in my legs. This condition is so rare no local GP knew what it was or how to treat it. I was referred to Physio which actually made it worse. A specialist had to come all the way from london to give me answers i had been looking for. These hernias press on my nerves when i stand causing excruciating burning pain in my legs / shins restricting my ability to walk, I’ve had them since i was born and they’re progessively getting worse. They say it was a condition men would get in the war / olympic athletes which is strange as i’ve never been that sporty in my youth. Having to deal with this aswell as my mental health has been a real challenge and i feel i’ve been let down by the system massively. I’ve sent off all evidence saying how i can only limit myself to 20 minutes of walking a day in spaces not all at once with frequent breaks without suffering severe pain. PIP rang me yesterday to say they will offer me enhanced daily living but not for mobility. They said it will go to tribunal.. I’m unsure if this is a good outcome or not and i believe i have been unfairly treated, any advice in black and white i can use to fight my case will be massively appreciated. I’ve had supporting statements from family / friends and plenty of medical evidence to suggest i have pain when standing / walking and there is no chance i can walk more than 200m at any given time! it would take me a very long time to do this distance because of the frequent breaks i need to take, i feel my youth has been stripped from me because of these dehabilitating conditions i have and i really do not want to result in using an aid such as a chair or stick because it is humiliating for someone of my age so i try my best to push through the pain but i shouldnt have too, i believe i have suffered enough, looking forward to your replies. Thankyou.
