I'm disabled, being 400lbs has nothing to do with it

I have a very vivid memory of going to the doctor to be assessed for SSI benefits. When I was in the waiting room I was surrounded by morbidly obese people on scooters. I was 18 and decrepit having suffered from a recent spinal cord injury. Chronic pain and mobility/bowel issues basically. Stupid me went in there and was optimistic as hell like "oh yeah, I'm in excruciating pain that literally never lets up but sure, I can swing my arms around in a circle! Life's not so bad." Then they asked me to walk in a straight line which of course, I tried my damn hardest and felt good when I did. I had just come from rehab with quadriplegics and complete paraplegics where the focus was put on everything you COULD do. I realized when I was denied that I had to stop being so damn optimistic and actually let them know how much I was struggling (which I was). I was kind of upset because I felt like the only thing that mattered was mobility... My impression was tha if you ate yourself into a scooter then you could get approved whereas me, a walking teenage girl catheterizing herself and carrying around a butt cushion with severe and obvious injuries could be denied. BUT I have no idea why those people were claiming disability, fat or not so I realize my feelings aren't necessarily applicable. But the thought was upsetting enough on its own and still makes me uncomfortable... I'm sure it happens all the time :/ To be clear, I'm less concerned about fat people getting disability because of their being fat and more concerned that people with severe disabling conditions would slip through the cracks (like I almost did!) just because people who are fat but otherwise fine are complaining more. SSI kind of forced me to be a squeaky wheel :/
