Non Differential Carcinoma

My Sad story begins, February 2016, as my moms thought processing was played with, her primary doctor did a ct scan and found a baseball sized metasticized tumor in her brain, surgery came and went, but not only did she have a metasticized tumor in her brain, she also had 2 supraclavicular and 3 in her chest.... and no one can tell me what to expect, life span, the radiation took her hair, the chemo caused neuropathy and my mother lives in pain on a daily basis, on the day i found out she had cancer i knew i was giving up my single, independent life to move home to take care of her, along with my father having congestive heart failure, and a anurism they are closely watching i go to sleep every night wondering what i will wake up to the next day!!!
