Katharine Gibbs School

I went to Katharine Gibbs School in 2006 for medical assisting. It was not my idea, and they went bankrupt afterward. I never got a job in that field despite their claims. I am trying to get disability, but have to wait for my hearing because of COVID. Navient is trying to collect on the private loan due to default, and we are broke. Education Dept. said sorry can’t help. What now?
