Don’t let the buggars get you down Jim, fight back my friend. There’s so much help out there, CAB, local council advice and many more. I used https://www.benefitsandwork.co.uk/, believe me it was worth every penny, with people and guides to help you through the next stages. Please take a look, they were the reason I got through the DLA/PIP process. Can’t praise them enough. Chin up and carry on, you’ll get there.
