Hi Wendy,
Firstly, you have found the best place to come for understanding and support. The women on this site and wonderful, and have experienced everything you will go through as you start treatment.
I am also triple negative bc, and was diagnosed Stage 2a Grade 3. Do you mean Grade 3? We tnbc's are nearly all Grade 3 when diagnosed. I had a bilateral mastectomy, 12 weekly chemos, and radiation. Due to family history I also had a hysterectomy afterwards. There isn't much that I didn't experience, so ask anything you want.
I want you to know that now, 3 years later, I feel very fit and strong and life is back to what we call the 'new normal'. With a healthy diet, regular exercise, and a positive outlook you can really help yourself to fight this thing. At first it is terrifying. Just take one day at a time, keep a notebook, stay as busy as you can even just round the house.
There is a great group called Triple Negative bc onsite - the search box will take you there - feel free to read our stories by clicking the profiles.
All the best with your checkups - we are lucky to have such a great health system here. Let us know how you go. Big hug.
