You are not getting the point.

Me & My son was told substantial gainful employed not substantial gainful activity.
Having him doing errands could even be gainful activity or him mowing the lawn or him using the computer or cleaning the house (He is not so good at cleaning the house) and so on. However, none of that means his is not disabled. I am divorced. I am not saying he is cable of getting a job. The problem would be keeping the job and people understanding him. Now with todays economy, getting a job is almost impossible.

I still stand by what I said about the special schools.

The Op should look into pell grants, vocational rehab, and special schools. Then he would have to borrow less. Future SSDI can be garnished for student loans but SSI cannot. This is according to SSA website.
