BH - fortunately one of the now usually very curable ones, caught at an early stage thanks to screening - breast cancer. I have had it twice, but different types, so non recurring, but the second time required very radical surgery as I had radiotherapy the first time. TMI probably, but you did ask!
I do think the second time was in part due to emotional issues around supporting my children during my h's MLC. He didn't keep it to the two of us, but visited his anger on his kids very painfully.
I have reached the point at which the pieces from the MLC have fallen into place, and although the wound is there, it is largely healed. But this type of thing cuts deep at any point, especially after a very long and [for me] happy marriage. I do think we can hang on for too long, but only we know when enough is enough!!
