I highly recommend it. 2 lung surgerys later ther is still a small node on her heart sack. tough to operat on but not inoperable. He seems pretty confident about success. But my sister and all of us in the family are pretty scared. I don't think it ever goes away, but I do think that we can deal with it by pulling ourselves back to the present.
Fear stems from the unknown and feeds on speculation.
If you and your sister can remind yourselves of the present each time that fear starts to creep in, I think that helps. I highly recommend it.
