Hi Colin.
I think day to day is the best we can hope for at this stage. Losing our lifelong partners has taken everything we had planned for our futures. That doesn't mean we don't have a future we just can't imagine what it will entail. We have to rebuild our lives around our loss and only then can we start planning again.
That's what my counsellor would say anyway. It's kind of hard to see a future for me as well.
