A friend of a friend is ill with cancer and is starting treatment again soon - she had been in remission.
We started chatting yesterday for the first time and after a lull in conversation, I said to her that I had heard she was ill and that I was very sorry to hear it. Conversation continued and she said that it was fine that I knew and that she is open about it, but that she does not know where I would have heard it from. We talked about things in general and about my work etc and towards the ends of the conversation I offered to take her kids to and from school if she needed help. The conversation was friendly and went on for some time.
I am now feeling very guilty that I brought up her illness myself. I think I did it to make me feel more comfortable being with her, and that because of this what I said was wrong.
Did I do the wrong thing? Should I have kept my mouth shut? I also feel dreadful because I remembered later that the person who had told me had told me in confidence. I should just staple my fucking mouth shut, I think.
