I understand your fears about your sister. It's ok to call her and just tell her you are scared. I don't think everybody has to "Think Positive" about the results. Actually, it kind of bugged me that everyone was so SURE mine would be benign. Everybody but me, that is. They were right - but it could have been a different outcome. I needed someone to let me process my fears and the "what if's". In the end, we could both agree that it was pointless to try to figure it all out before we knew - but having someone to just acknowledge the possibility of a bad outcome and the fear would have been comforting to me. Does that make sense? So I encourage you to call your sister and just be honest about how you feel. That you've been afraid to call. That you're afraid to lose her. That you don't know how you'll cope if she has cancer - but that you love her and will do your best to be supportive of her no matter what. Would you be comfortable doing that?
I have one sister. I'm 45 and she's 47. I'll be 46 soon. We're only 18 months apart. I can't imagine facing the possibility of losing her. I pray your sisters results are not what you think - but if they are, I will continue praying for both of you and your families.
Let us know when you find out.
