Hi! Sorry that your in this situation, the two week wait is the hardest part! I have just been diagnosed with bc, your brain will be doing some very weird things, there is no right or wrong way to deal with this situation. You will always think the worst as you have no idea what you are facing. 
As hard as it is, right now you have not got a diagnosis, try to keep busy and active, it's really difficult but manageable. You've done the right thing reaching out here. I've been stalking this group for 4 weeks now since I started my journey, only just got the courage to write it all down. I found mediation was very helpful, I got a gem art and focused energy on that. Hopefully it's a benign result for you x take care and reach out if you need a chat x

I am in the same situation. I am now day 11 since my core biopsy and I was remaining positive till day 7! I haven't even got an appointment booked in-I have my phone at the ready and feel on tender hooks the whole time. Wish you luck with the results. Remember 9/10 are benign!! That's what I am clinging onto.
