SSI under great hardship

50 years old on SSI disabled. Unable to work and will not be able to return back to work because of disabilities. Back child support has been giving me great hardship under the suspension of license for back child support. Leaving me wondering why. Or how I am able to pay something when I'm unable to do the other as in work. And under the great ship of covid-19. I find it very disturbing that the state consider taking money from a disabled person is illegal to do. But yet allow them to attack the individual over a driver's license. Where is the fairness and where is the law that stands behind the disabled.
