@Alisonc46 welcome to the forum! Goodness you have done it tough by the sounds of it! Our bodies are complex in their reactions aren't they? I do hope that you get some comfort from the forum. There is a wealth of information as you try and navigate your way through treatment and what it all means.
I assume if you have found us you have received the resource, My Journey Kit, here's a link just in case:
https://www.bcna.org.au/resources/my-journey-kit/We all have a diagnosis called Breast Cancer but from thereon it differs so much and our treatments are all so individual
https://www.bcna.org.au/understanding-breast-cancer/types-of-breast-cancer/I am sure as the day goes on others who have a similar diagnosis to you will come along and give you some encouragement.
Take care and I hope you are on the better side of treatment and improving every day
