I am going through a similar thing with my wife. She was told she had cancer summer 2020 and put on palliative treatment 18 months ago and keeps fighting. 50 sessions of chemo, a hip replacement, 2 Christmas’s and some real ups and downs but you need to make sure you talk to friends STW or anyone. You physical and mental health is paramount to you supporting everyone in your life. Try and focus on the now instead of when the worst could happen. Try and be positive and even go for a short ride or walk or even a pint with friends. It shouldn’t also be the only point of conversation. Talk about other crap. Its very easy to write this but now just have to follow my own advice!! Good luck on your journey.
