I'm so sorry to hear you are going through this.
I am a complete stranger but I believe that positivity and a good support network and great doctors with the right medicine is 90% of what it takes to make you better.
The other 10% is down to your own body and how it reacts.
But if the other 90% is there, then there is great hope.
Practically, have you got some help that will be available to you so the youngest / others can be looked after - especially when you are feeling very rotten?
Do you have family or friends who could have them for a weekend when the chemo/cardio is getting a bit much?
I know you'll probably want to be with them, but if you are struggling - or even someone who can stay in the house with you.
I can't imagine what you are going through to be honest but it must be so shocking to feel a bit poorly in the morning and find out there is horrible disease that you are going to have to fight. I imagine it's just one big blur.
I live in the South West of England and if there is anything I can do let me know (bring stuff to hospital for example) let me know. I would say the kids could play with DD but she's 1 so probably not the same age range.
Thinking of you and hoping that this turns out the very best that it can.
