feds are required to hire disabled but that said you still must be able to perform the position. you can't be hired for a position that you have no qualifications for...just because you are disabled (it happens rarely but usually the person hired does not last long). even with accommodations you still must be able to perform duties. the gov't is not a free ticket. and once you are hired you must show up for work, maintain standards etc.

good luck with employment, I wish you the best. I hope you find something, maybe find an agency that helps the disabled locate jobs.
