My partner has Stage 4 Colorectal Cancer and has been having treatment for 18 months. This weekend is her sisters 60th birthday in Edinburgh. All the family are going. We live in London and we are booked on a train tomorrow afternoon. My partner M has been getting more and more breathless and her heart is racing. It seems panic and maybe the journey is all too much. She so wants to see her 87 year old Mum. Not sure whether we should go for it or if I should be heading to the hospital. Hard decision?
