Diagnosed today

I've been lurking on this group knowing this day was coming. Triple positive invasive ductal cancer. I'm a radiographer do I knew by the way that were planning they knew. The surgeon is handing me over to oncology and didn't want to commit to surgery so I know it locally advanced stage 3c. I'm devastated I have a 2 yr old and I'm a single parent with little support. I don't know what to do. 😩
