Hi William, firstly am sorry you have had this awful diagnosis, it is very scary indeed when they tell you its cancer. I can only give you my recent experience of this, others may have thier own thoughts. 
My husband was diagnosed with stage four oesophageal cancer in november, completely out of the blue. We were told it was inoperable, and had spread to his lung and lymph nodes. We were absolutely terrified and immediately thought 'this is it, game over'. But, a few months later, his chemotherapy is going well, he is looking and feeling much better, and you woudlnt actually even know he has anything wrong with him. We have also learned, that many people live with stage four cancer for years. 
Please please dont give up, or believe everything you get on google, if I had believed that it would have meant my husband would already be dead! Have they said what treatment you might be able to have? 
Sending you good luck, I hope that you find it supportive here, I lnow I have. 

Hi daisy71 your message is so warm and beautiful  I'm sleepy at the moment  but please stay in touch love x  x 

This is how we deal with it, we enjoy the good days, and when he was not feeling so good, we just got through it together, nothing wrong with a good cry! each day passes, some better, some worse, but you do get through them, and have to remember to really appreciate and enjoy the small stuff, a nice meal, a beautiful day, birds singing etc,.

you take care and keep us posted. 
edited to add - if you pop which type of cancer you have in the search engine at the top of the chat section it will bring up similar conversations and might be useful 

Sitting here crying how do you feel strong when all is lost are you bitter angry sad at ease and how can I get to a place of calm x
