There are a lot of disabilities, so I don’t know… in my country you could have a 100% physical disability but be in your mind (quadriplegic for example), and in fact there was a person in this condition that fought the government in court and won forcing the government to legislate in his favor and others in similar conditions.

Man the US are not the world, in the civilized world you don’t get shot for migrating…

I’m sorry, but all civilized countries in the word offer some social assistance to people in your situation. Put together all disabled people and their families and fight for your rights.

You CAN do something: change you job, study something to improve your skills, change country if you must.
