Once the shock wears off, I dunno you seem to go into “make the most of it” gear. And even given the time limit, you still don’t know exactly when, it could 2 and half years, 3 years, and yes it could be less - but there’s still no exact date so it is making the most of every single day.
There is always an echo of saddness, knowing that time is short but I dunno, it kinda gets pushed to the back of the mind because you get into the mindset of living each day as it comes rather than thinking of the future and what it will bring. The hardest thing for my brother was when my mum wanted to discuss funeral arrangements and her will - he didn’t want to hear it because he didn’t want to think of that. So my mum discussed it with me and another brother and then it was kind of forgotten and she concentrated on the plans she wanted to do while she had time left, going on holiday as a family, going on picnics, spending as much time as she could with my brother’s kids etc.
Try not to think of what is to come; but rather what is happening now.
Because honestly sweetheart, regardless of the knowing, when it does happen it will be a shock, knowing doesn’t make any difference really. My dad died suddenly and it was no less horrible than knowing my mum was going to die any day, or when one of my brother’s died. All it means is you have a slight advantage in that you all can say those things that you might otherwise put off, do those things you want to do but normally think you have time to do whenever and love each other as completely and comprehensively as possible.
