My mom diagnosed with ovarian cancer

Its been 5 months since my mom diagnosed with ovarian cancer, she is 48 years old. After the surgery she took her first cycle of chemotherapy on mid September 2016. Although at first we didn't disclose the fact to her but eventually we had to tell her calm and quitely. After the first cycle when we went hospital for 2nd, the oncologist postponed the therapy due to her elevated Serum Creatinine. Since then the S. Creatinine is still around 1.6 mg/dL, and therefore my mom can't having chemotherapy anymore. For last 2 months  we had to admit her into hospital several times due to continuous vomiting and imbalanced electrolytes. We consulted nephrologist, oncologist but none can give definite solution. My mom is the heart of our family. I can't express how it feels when I see her sufferings. The whole thing seems like a storm in my life. I wish the supreme Creator cure my mom and give her peace.
