You need to apply for Social Security Disability and SSI income. Your local Social Security office or county Social Services office may be able to help you. SSI is an automatic application when you apply for SSDI. You will likely get denied for SSDI but may get approved for SSI. SSI is designed to help with immediate financial needs while an SSDI application is processed.
You can also start the application online at
www.SSA.gov It's worth getting an application started in case you can not find a job that you can tolerate.
