Help cover medical expenses for cancer treatment

Was diagnosed with Multiple Myeloma 5 years ago and went thru a stem cell transplant. Was in partial remission until 5 months ago till I experienced a fracture in my back that was pressing on a nerve causing my right arm to go numb.  The cancer had returned and I am now being treated with an aggressive chemo regimen.  The enormous amount of testing and appointments, along with a change in insurance have left my family in serious financial hardship.  It's hard when you have 2 daughters and your unsure if you can provide for them.
