It's really tough.. I had a similar experience. A friend who had a new born child that was diagnosed with leukemia who fought for a year.. It really broke my heart. Everyone tried to help.. The help was there but it was just too much for the child.. He passed away before reaching his first birthday.. Life is tough, sometimes we wonder if God is doing it intentionally, I mean hurt us emotionally. But I believe that everything happens for a reason. Have faith, believe... I hope that she can cope up.. God is good... :-)
