Let it out - like the cancer, it’s better out! We have all experienced varying degrees of the same shock, disbelief and most of all fear. The fear is the hardest thing - our brains may know that none of us know how long we may have in life but emotionally we are tuned to assume we have forever. Nothing has actually changed, it’s just that your emotions now know what your brain knows and it’s very hard to accommodate at first. It does get better - surgery is the first step, knowing what your treatment is thereafter is the next one. Deal with that first and do whatever you need to to get past those milestones. But getting some help with the fear (which is real, understandable but not helpful) may be worth looking at then. Your medical team should be able to suggest good counselling services to assist in facing something of this scale. Many of us have found even a few sessions really beneficial - family and friends can be comforting and supportive but counselling can get to the real nub of things. Just as you will help your body to recover, your mind needs to recover too. Years from now, you want to be able to look back and say wow, that was horrible but I also learned some really useful things for my life too. Best wishes.
