I'll keep this brief....
When you have cancer, and you go out and find out about someone with incurable cancer, it sorts you right out. Doesn't fucking matter what was bothering you, you haven't got incurable cancer. You've got a life.
I might not be the cleverest, or the funniest, or the prettiest, or the coolest, or good enough in whatever other way, but I have a life and I can live it. So I won't waste it.
