Sorry to hear about your mother Shadow. Losing a parent is always tough. My father died two years ago March 25 and it still hurts.
My father had prostate cancer although it was treated successfully and one of my best friends from college died from cancer when he was 29. He was married and had three daughters.
My wife and I donate every year to several organizations because of this. Cancer, Diabetes, Olympics for special needs children, and the Deaf and Blind organiziation. My aunt and uncle were both deaf and mute. Good causes to donate to.
Keep your karma and give it to someone else. I know how much these organizations do and I am happy to give what I can.
Take it one day at a time and I'll say a prayer for your family.
