You can go from SSI to Social Security Disabled Adult Child’s benefits on your mother's or father’s account. The parent must be either receiving benefits or deceased and your own onset date must be established as on or before age 22.
SSDI is Social Security Disability Insurance. To get on the program a person must have disability insured statures which means he or she must have worked. What you can do is to go to your local Division of Vocational Rehabilitation and explore possible jobs you could do to gain insured status.
Actually many people work even with severe impairments so there is probably work for you if you want to do it.

No. You are only eligible for SSDI if you have worked, paid into SS, and are eligible to collect Social Security when you retire. I believe you have to work a minimum of 10 years and meet minimum income standards.

No. SSDI (social security disability insurance) is only paid to people who have worked and paid into the social security program long enough to be insured. Social Security is an insurance program which means that people must pay their premiums so-to-speak. Premiums are paid in the form of social security taxes on earnings from either wages or self-employment profits.
How many credits a person needs in order to be insured depends upon how old they are when they become disabled or die. A person needs 40 credits in order to become entitled to retirement benefits. You can earn up to 4 credits a year. In 2016 you earn 1 credit for every $1260 you earn and pay social security taxes on. The cost of a credit goes up every year. Once upon a time a person earned 1 credit for every $50 earned.

No. Your are not eligible for SSDI if you have never paid for it.
