Hi Laure'
You've gotten wonderful advice from the other members, so I'll just add my welcome and tell you that I'll keep you in my prayers. Please if you could let us know what time tomorrow your biopsy is we will be there with you in spirit courtesy of the PCE. I'm a newbie here too and started reading about this PCE with pink feather boas and wondered what in the world was going on. I wrote, asked questions and got answers telling me it is this groups way of letting you know they are there with you. I've had them with me for another biopsy since my BC was diagnosed. And it helps to imagine those silly ladies in the room with you wearing pink feather boas! It is a nice distraction.
During the waiting time things that I found helpful to keep me from losing it were; reading fiction, watching a movie (not Lifetime), prayer, meditation and upbeat music. I've listened to "head banging rock" in the past and there have been several times in the last 2 months that I got in my "soccer mom" van and turned some music on LOUD and drove while singing. If it's screaming rock it seems to be somewhat therapeutic.
No matter what happens just remember you are not alone. We are here for you with advice, love and support. And remember this is treatable, do-able and you are strong!
Hugs,
