Chemotherapy treatments for Karen

I am going through chemotherapy for the second time in three years.  The cancer is metastasized from endometrial cancer that I had four years ago.   My insurance covered the surgeries, doctor visits and part of the chemo.  Unfortunately, 20% isn’t covered.  I have worked part-time before, but now I can’t do that and I only have Social Security and some savings to live on.  I’m giving all my energy to living.
