Breast cancer at 8 months pregnant

Hi, i was diagnosed a week ago after i felt a lump and had a biopsy. They were confident it was a fibroadenoma bit its turned out to be triple negative breast cancer grade 3. I dont know the stage but its likely 1 or 2. 
I am currently 35 weeks pregnant and i will have to deliver my baby early, i also have a 2 year old.

I know there is treatment available but i am absolutely terrified of whats ahead and how i will manage. I want to be around to see my babies grow up and be there for them when they need me. 

Any advise or similar stories would be appreciated
