triple negative invasive ductal carcinoma

my mom was just diagnosed with triple negative invasive ductal carcinoma and i am terrified. google does not help of course and it definitely doesnt help reading that lymph node spread is common when she was having lymph node pain/enlargement in the hospital two weeks ago.

i am terrified. my mom is my best friend and i am so scared to lose her. has anyone gone through this type of cancer before? from research, it appears to be 10-20% of this type and fast growing.
