If you can actually work in an office, what does your disability have to do with not being able to get another job? I can’t imagine a disability where you are mobile enough to go into an office but limits your ability to get another job.
Especially if you can work at Walmart where you have to stand on your feet and move stuff all day.
For reference: I have cerebral palsy that for all intents and purposes affects mostly my left hand. But standing all day in a retail job day in and day out would be detrimental because of a slight affect of CP on my left foot.
