Hi MattyBoy, Welcome, I to was diagnosed with TNBC last October grade 3.
It sure is a roller coaster ride, and like you I never liked roller coaster rides either I was always the bag lady waiting below lol....
But you can do this just like I have and others.
Keep yourself busy, light exercise and plenty of fluids.
I found meditating helped me through the times where my brain was over thinking things.
Ive had surgery in December Partial mastectomy and 2 sentinal nodes removed, all clear, then A/C dense chemo in February 8 weeks every fortnight, then weekly paclitaxel for 12 weeks.
Had a full auxiliary clearance in July as there was one lymph node under my armpit involved other 14 were clear.
Just started Radiotherapy for 30 sessions.
You’re in the best place for others that have been there. or others like me who are currently going through this.
I can tell you there a lot of people that are cancer free with the diagnosis of TNBC .
Stay positive, you can send me a private message if you want to talk more.
