Help with the cost of chemotherapy

I've had a recurrence of CLL - Chronic Lymphocytic Leukemia  - first diagnosed near the end of 2015.  Underwent chemo in 2016 and have kept a watchful eye on my disease.  On May 8, 2018 my CLL became more aggressive and I've had to start a new round of chemo.  May 15 & 16 were the first 2 days and now tomorrow and Wednesday are the next two....wait 28 days - then 2 more chemo dates - wait 28 days - and hopefully the last chemo dates thereafter.

The cost of chemo is shockingly high and my insurance only covers 80% - the other 20% is my responsibility. my cost will be about $5800 when all is said and done so I'm asking for help in paying down that cost.

Thanks in advance.  Love, Susan
