Not, luckily, an epitaph.
Indeed. That's what you've done, after all: written down what happened as memento, but kept your mind and heart open to the future. A long, happy future, starting now with a tall dark radiologist.

Will you get tattoos for the radiotherapy? those are also marks of having fought a batltle, good reminders. Or at least that's what one of my closest friends tells me. (hugs) (more hugs)
