@padovani- Welcome to Mayo Connect! I'm sure that you feel all of these things and I wish that you didn't have to! My advice for you right now is to take just one day at a time. Do you know what your treatment will be for your liver cancer? Is it a primary or have they biopsied it?

I also never thought that a recurrence would happen. I had changed my life around and was "doing all the right things". Someone needs to redefine that saying.
For the time being, until this is under control do you feel like you would want to ask for medicine to help you get your feelings under control? It might help you see thing more clearly I think. Your denial will come and go but your other feelings will take a bit of time. I love the quote, "The difficult we do immediately, the impossible takes a little longer." I had to look at this on my refrigerator every day so I might slow down.
