I am 19 years old and are still living at home with my father. He has recently been diagnosed with stage 4 colon cancer and underwent a serious surgery where most of his colon has been removed. After he heals from this surgery he will undergo necessary Chemo treatments. Now to get to my question. My father has never had "suicidal" tendencies but I am worried with the multiple guns we have in the house one day he will give up hope and do something irreversible. What should I do?
