Do I have any rights if I was injured on the job?

I was hired to do a remodel job. I remanufactured mobile home. I was hanging drywall and I asked her for help to get help for me to hang the drywall but she said no so I did it by myself. At the time I lifted some drywall and I threw my back out, I was going to go to the emergency room. A week went by and I could not handle the pain anymore so I went to the emergency room. They gave me a CT scan and MRI. I was diagnosed with spinal stenosis and my lower back discs are rubbing. I can't walk straight anymore. The pain is unbearable. Emotional stress is very bad and depression has set in very bad.
