Being on disability does not mean you cannot work. You can certainly try to work part time and many disabled people do. I know people with all of kind of disabilities: blind, partially paralyzed, in a wheelchair, cognitively impaired with IQ of 50 work and many more. Some need vocational services to help them to get and keep a job and some can do it on their own. Having a job isn’t anything extravagant or unusual and it’s certainly not ignorant. I’d talk to vocational services in your state (do you know how to locate them? Do you need help with that?) and go from there. Your family is so off about this it’s not even funny
