Your employer would be in violation of the federal emplyment laws firing you because you have lupus. You have a right to contest your employer in your state unemployment compensation. Since you have a new job that is not necessary. Did he write a letter or were there witnesses to the firing? Cancelling health insurance is NOT legal unless he did it for all employees.
Make sure you get everything in writing in your current job.
