from the the website that popped up from a ‘ssdi’ google search…
To qualify for Social Security disability benefits, you must first have worked in jobs covered by Social Security. Then you must have a medical condition that meets Social Security’s definition of disability. In general, we pay monthly cash benefits to people who are unable to work for a year or more because of a disability.
my brother and I both have ssi. before he got his he worked in a fast food place for maybe 4 months. but my mom had to hire a lawyer for him to get it. I was easier I got it right away after working only 9 months at a retail store. the doctor at the hospital said I was disabled.
When i got SSI the reason I didn’t qualify for SSDI was my age of being disabled and lack of work history (I mainly went to school). Back then you qualified for SSDI if you became disabled before age 22. I don’t know if the rules have changed but you may want to look at both.
