I am so very sorry to read your story - January was an utterly terrible month for you and I can't begin to imagine how you handled it. You are a very strong woman, and an amazing example for your 5 children.
I also am TNBC and just finished the whole treatment of surgery/chemo/radio/hysterectomy (as a preventative measure). I just wanted to tell you that it is all do-able, and that there is light at the end of the tunnel. Just focus on one day at a time, keep your appointment diary up to date (do you have the My Journey kit from this site?) and write down every question you can think of before appointments, because you won't remember them later. (Chemo-brain is a true fact iof life - luckily it does go away eventually!)
There is a TNBC group on this site, and their stories might help to give you some comfort. Some are new like you, some having treatment like you, and some through the whole lot, like me. Do you know what stage and grade you were? There is a lot of information in the kit to understand your diagnosis and treatment decisions.
I am so glad you found us here - the support is wonderful - your pink sisters understand because we have been there ourselves. Take care and keep posting so we know how you are going. Sending you a big hug. Michelle xx
