Hi RocknRollPaddy and welcome, although I am sorry that you have need to be here.
When I received my diagnosis (almost 3 years ago) my kids were 10 and 11. It certainly affects everyone in the family. My daughter had a great deal of difficulty being away from me (especially at night-constantly had need to sleep with me/near me in order to sleep). I did get a counsellor to help her as there were things she just talked to her about that she wouldn't discuss with me (her fears about death, etc). It was also helpful to keep the teachers in the loop so they could let us know if there were any changes in behavior.
After hearing those words "You have lung cancer" my perspective of what to gripe about has certainly changed since then. I was, until diagnosis, like everyone else - ignorant and unaware of how life can change in a heartbeat. I am still no saint-still lose my patience and still human, but I am more aware (if that makes any sense). I guess I have less empathy for the stupid arguments that people have - they seem pointless and sad all at the same time. I imagine you see that daily in your work!
I can't imagine how difficult it is to get through the work day when fatigue is such an issue. Is there any possibility of cutting back hours to a more manageable level for you? Or does work keep you sane?
I am so sorry that you and your family are having to go through this. We are here for you.
