@Angiebloom Welcome to the forum. I'm sorry that you're here, but now that you are I hope you find it as warm and supportive place as I have.
The waiting is hands down the absolute pits. Keep yourself as distracted as possible between now and then. TV, friends, exercise, hobbies, meditation, go for it. You have to feel the pain but there's time enough for that process later, when you know where you are. And once you have a treatment plan and get underway with it, you'll feel better.
Accept all the help you're offered (I found that very hard, especially at the start), be kind to yourself, and stay away from Dr Google...
The day you're having your op is the second anniversary of my diagnosis. As a fellow BMXer, I'll keep you in my thoughts. Big hug, K xox
