Erin's Cancer Fight: Seeking Assistance

My twin sister Erin has just been diagnosed with lung cancer. About 2 months ago wasn't able to work or take care of herself . I had to go part-time at my job to help her through their cancer treatment. She has no saving and is not getting food stamps currently but she has applied. She would appreciate any help that she could get. Erin's chemo did not go as planned she only got three doses. She was recently diagnosed Addison's disease. Erin recently spent four days in the hospital because the adrenal gland in deficiency.Erin's only hope is immune therapy that is not covered by her. she would greatly appreciate.
