Dent in Areola - have an appointment at the breast clinic in a weeks time. How do you manage the worry? I can't stop thinking about every worst case scenario

Hi all, since finding a (admittedly) really small dent in my areola I’ve been worrying. I managed to get a GP appointment 3 days after I found it (after nearly crying down the phone to the poor receptionist who had to tell me my request was triaged and was initially put down for an at least 2 -3 week wait routine GP appointment). This site has been a great help and reassured me that so far I’ve done everything I can. My gp referred me to the breast clinic based on my explanation (no examination).

Does anyone have any suggestions on how to manage the worry - I know googling is not ideal and now it’s making me think of every possible worst case scenario. 

I am 43, breast aware, check visually and feel regularly but I noticed this dent on the side of my areola when I bent to move a mirror and there was a small bit of shadowing. It’s only there when I lean over and now I think it’s there when I move my arm above my head. Now I can’t stop looking at it. I cannot feel anything but I know I have lumpy boobs after being referred to the clinic before for what was a Fibroadenoma. I’m convincing myself it’s getting bigger/worse. No other symptoms. I have the appointment at the clinic a week tomorrow but if anyone has any reassuring words of advice it would be much appreciated.  
Thank you x
