I don't let myself dwell on the VHL facts of life - at least I try not to.
But you can't always help it.
When I was at uni, a heavy VHL time for me I wrote a monologue short which I was quite proud of at the time. The girl I got to perform it, (she was old enough to be a woman but as I on'y felt like a girl and I am older than her it seems ok) was beautiful and thin. A friend who came to see it said she thought it was about anorexia. I didn't explicitly mention VHL, you need to let your audience see their own life not yours, I wasn't trying to educate anyone on the life with a rare genetic disorder I was just trying to express the strangeness of feeling like your own body is your enemy, that your very cells fight you.
