Hello Nat and a belated welcome from me.
I have read through your whole post and you come across as a very caring daughter. I do hope the results were the best that could be expected.
Has dad been given a treatment plan yet?
If either of you need answers other than advice from us then you can always contact one for the nurses on here. Our members speak very highly of the help and advice they have been given.
Our local hospital has a "MacMillan" room where there are lots of helpful leaflets etc and usually a volunteer to point you in the right direction for information. Might it be possible to check with dad's hospital to see if there is any counselling available.
There is often access to complementary medicine in the form of Reflexology, massage etc available and you may be able to get advice from your hospital as to the availability of these. They really do seem to help
Best Wishes
Sandra
