Hi @byefelicia, it's such a shock when you're in the intial stages and don't know what's next down the road... especially when you are young and don't expect this to happen to you. The BCNA articles are great to demystify and explain all the medical jargon and I would often trawl the BCNA discussion boards too when questions popped in my head, often in the middle of the night.
Similar to you, I am in my mid-40s with two kids aged 6 and 9. I found a lump late last year and was diagnosed early this year, it's been a huge change to focus on dealing with my health as the number one priority rather than the kids and work.
All the best with your treatment and the community here is great for any queries. I also have recently started attending bosom buddies coffee catchups and younger women's groups which are a great support network too.
Best wishes
