Welcome @strongtogether,
Sux to be here but there is so much warmth, information and understanding standing on the forum no matter what time of the day or night. There are a few of us close to Brisbane as well.
The start is scary as hell but as the lovely ladies have already said, once there is a plan you feel a little more in control. I was 45 at time of diagnosis but I had a house full of teenagers.
While not TNBC I was node positive 5/24 with one at 25mm but I knew that from the beginning. So Lumpectomy, re excision for margins, axillary clearance, 6mtss chemo and 30 rounds of rads.
While it is all so incredibly daunting at the beginning and the fear of the unkown is indescribable, once that first chemo is out of the way the time passes pretty quickly and before you know it your done.
While chemo is no walk in the park and that's probably the scariest appointment, some of us get through not too badly. I was still able to work part time, run my farm, do all my usual things and plan formals, 18th birthdays, graduations and Christmas. Kept my hair with the cold cap and had a lot of fun times throughout it with all those events.
I also had next to no problems with radiation.
Our brains like to conjur up worst case scenarios at the beginning, but there's a good chance it won't be anywhere near what we think at the beginning.
There was some crappy days in amongst it all but there were a whole lot that weren't.
All the best and look after yourselves.
