@Quote_Queen_67 firstly sending big hugs
Others have already given some great advice
I too am in the newly diagnosed phase and feel like I am also in survivor mode, so I can relate. I have shed a few tears here and there and find that the moments I do have to grieve actually make things easier. We all react and deal with things differently, and when we have kids we can't just collapse in a heap, or crawl into bed and refuse to come out. This is a good thing! However it is important to be kind to ourselves to fit in grieving as it comes up. Getting on with things can make you feel more in control, when everything can feel out of control. However as the shock wears off and realities set in it can feel overwhelming. So you are in the right place to gets lots of support with that.
I too still have to tell my kids aged 5 and 10. I waited till seeing the surgeon so I at least have a plan.
I was also worried about wether I will be able to work, I can't really afford not to. My surgeon told me yesterday that if I want to I can still work. They try and support people either way, if they want to work or if they want time off. It will help if your workplace is flexible.
I'm glad that your mum is coming to support you.
I still have not told my parents, they live in New Zealand and I just can't bring myself to pick up the phone.
