Yes, my 2nd T's son was diagnosed with Hodgkin's Lymphoma and eventually passes away. He was not much older than me. It was a very difficult time for my T, a man who by his own admission never really dealt with depression until his son passed away. The major effect on my therapy was simply times he could not be there to hold sessions, but he remained supportive and available as much as possible (more than I would have imagined actually) throughout.
