Hi @Gin1966, it was so helpful to read this post and the replies from the lovely people in this group. Like you i was diagnosed just recently (4th June) and found out five days ago that I need a mastectomy. I'm also reeling from the news and I'm exhausted by the non-stop thinking about my breast cancer. I feel like my life has been paused and nothing else matters except dealing with this nightmare.
But we've got this. And we've got lots of support here. (Also I don't know if your username is indicative of your date of birth but if it is I am the same age as you too!)
