Explain how your condition affects specific daily living and mobility activities, rather than focusing only on your diagnosis. Give real examples of what happens on good and bad days, how often difficulties occur, and whether you need help, an aid, or extra time to do something safely and repeatedly. Include relevant medical or care evidence if available, but do not delay returning the form if you are still waiting for documents. Check the official GOV.UK guidance, or ask Citizens Advice or a local welfare rights adviser for help; contact the DWP promptly if you need an extension or reasonable adjustment.
