Robin, I too will share your prayer request with a few others who I know will pray the prayer of faith.
I faced this myself 23 years ago and I was miraculously healed. Many before me have shared great love, encouragement, and advice to you. I just share this...
DO NOT allow your mind to run down the road ahead of you in fear. DO NOT allow your mind to picture yourself months from now, sick and dying, and leaving others behind. DO NOT GO THERE!!!!!
I have walked in that valley, I know how easy it is to get caught up in the fear of it all. Try really hard to pull yourself back and focus on where you are now. Now you don't know anything for certain. It's impossible to deal with something that you don't really know what it is or what can be done about it. Just one day at a time. Tonight and tomorrow, you are just waiting to go for tests. Then you wait for results. And you go on from there day by day.
There is hope so please don't give up.
Blessings and Hugs,
PS: I am sending you a PM
