Tell him or her now. I mean if your friend was dying and there will come a day you may never see them again, would you want to know? Yes, he/she may freak out and cry and want to spend every moment with you, but time is running out. Also, if you wait he/she may become upset and I know I would want my last moments to be happy. Overall, this is MY opinion. Overall, this is YOUR choice. Think about it, carry the decision out, and live your life because life is a beautiful thing. Best of luck and I hope heaven is as nice as they say. -Lilly
