Help with medical expenses

As most of you know back in 2016 I was diagnosed with stage 4 breast cancer. It's been a long annoying and painful road. As of this past weekend the cancer has spread to my brain and to the other arm pit. I have a great team of doctors and I do have insurance. But out of pocket costs and upcoming costs are going to be very hard for me. I am on a very fixed income and I am still paying for breast radiation bills from last year. I figured this couldn't hurt to ask for some help. Right?
