My dad has terminal colon cancer with mets thoughout his body. I'm living in the uk and he is back home in Australia with my mum. I'm just about to catch a flight home to see him and support them both. Really struggling with my emotions and can't stop crying as I love him so much and can't bear the thought of loosing him. Don't know what to say to him and how to say goodbye when I leave in a few weeks to come back to the uk. My 2 brothers both live abroad and are not medical, So I need to let them know what his prognosis is and how long I think he has left. Struggling as I'm devastated.
