My hubby's cousin weirded out when she had cancer too.She wouldn't even talk to her sisters or even her mother. They live on a farm and wouldn't even let her family come and help cut tobacco, something they have always done.
Fortunately she is improving after her mastectomy. She is now trying to get things straight with the family.This is a very close family and she is the youngest, so everyone was so confused and hurt. Maybe the chemo does something to some people. At least she didn't drive her husband away! Only God knows what she went thru!
I'm very sorry you lost your friend. I hope knowing others have also reacted this way will help you.
