I have severe arthritis, fibromyalgia, cervical spondyllosis, depression & anxiety,. Basically I 'walk ' with 2 crutches, I say walk as I can only manage around 5 meters before I'm in extreme pain and exhausted, I don't go out much now . I'm worried about going to the assessment and them twisting that I can walk more than 20 meters as I assume that will be at least the distance from door to chair .
