i've been trying to figure out which one i've been receiving for the last 12 yrs. i was 27yrs old serving in the military and became paralyzed in an accident. i've lost the original paperworks and what comes in the mail and direct deposit doesn't say. i've heard there's a cap amount for ssi and ssdi depends on how much you've put in? i'm from connecticut and currently receives $950/month less medicare. ssdi or ssi? thanks...
