Help me pay my medical bills & debt

I'm facing an upcoming surgery, which will put me out of work for some time. I don't make much money since it is already a part-time position, and I already have credit card debt and other bills that are difficult to pay in even a normal situation. I also take care of my 83-year old mother, who has a heart condition as well as other health issues, and she is also on a fixed income. It has been difficult already, but I know that I am facing not only serious surgery and health issues, but surmounting debt since I will be missing work. I also am not sure if insurance will cover my medical expenses. I don't know where else to turn. Please help me!
