Too sad, but James do you have enough detail to tell her story? Give it a try. You can always explain that it's coming from your conversations together. Information like this is gold.

I was reading a story recently about two friends meeting after lockdown. One had all these plans (only in her forties) about what she was going to do in the following weeks. Sadly, she passed away due to a cerebral hemorrhage.

The time is always NOW.
