Newly diagnosed with bowel cancer. I don't know how I'm going to cope with all this

Hi, I was diagnosed with Bowel cancer a few days ago, and I’m just completely lost.

I am 46 year old married, no kids just a large dog and I am waiting for my CT scan results, my head just feels empty. 
My dad also has cancer and there is no treatment left for him.

I seriously don’t know how I am going to cope with all this ‍♀️
