Uhhhffff. I am really sorry to hear this. My dad has had a couple of fairly bad diagnoses in the last few months - a big one today... and I suspect is probably feeling awfully depressed. If you have any thoughts or advice, and it wasn't too hard to share for you, I would be really happy to hear. Or just tell me to search for a thread! I really don't want to add to your burden.
I have no idea how I feel even about this stage of things. I can only imagine you are trying to find your feet. All the very best as you go through this.
