Help my mom beat cancer

They say "when you become a mother, you are no longer the center of your own universe. You relinquish that position to your children." These words describe no one better than our Mom, Usha. This woman lived by her values, taught her children how to be good people, how to trust god, and never do any harm to others. She was our rock, the person who held the family together, and fought others like a mama bear that she was when someone spoke ill of her cubs. She worked days, cooked and took care of her kids at night, and never questioned her faith. 
We grew up watching her go at full speed from sun up to sun down...and now, she can no longer do that. Over a year ago, we received the worst news, our mom was diagnosed with Stage 4 liver cancer. She didn't care, she organized and danced the night away at our brother's wedding, watched her second grand daughter come into this world and put up a fight against cancer. She continues to live by her faith and values but she is no longer the person she used to be. 
The cancer is spreading to her stomach, causing a lot of pain. She can no longer get out of bed, go to work, clean (her favorite part of the day), or cook for herself. She never asked anyone for help and now she is at the mercy of others. 
We, her 3 kids, are trying to raise money to assist with her medical bills. She would never do it herself but we have no family around to support us. Our father does what he can to meet the needs of the home and day to day bills. We appreciate any assistance, whether its financial or in heart felt prayers. Thank you.
