Kozo -- sending you love and prayers. Thinking of you brings the word "service" to my mind. You are living service. I have come across the work of a non-profit called Harmony Hill that supports people with a cancer diagnosis in various ways(http://www.harmonyhill.org/cancer/), including family retreats. Offering it in service: http://www.harmonyhill.org/cancer/cancer-retreats/ I know someone who works there that I'd be happy to connect you to, if this is at all of service.
