Welcome to the forum Xpataus and I am sorry you have to find yourself here but you are in the BEST forum and safest place for information ever.
Your story sounds very similar to mine (the palpable lump found, the nodes involved, the mastectomy then the left auxiliary clearance, the one remaining breast later to be removed, then chemo then rads, then prophylactic surgery due to Breast Cancer Gene Mutation BRCA2, Hysterectomy etc.) I have pretty much lived through your journey last year and have just come out the other end 18 months later. I had 6 surgeries in total. My Initial surgery removed the sick breast, my 2nd the lymph node clearance, 3rd placed a portacath for chemo, 4th was a full hysterectomy to prevent ovarian cancer, 5th was mastectomy of the healthy breast to lower my risk of new breast cancer/recurrence, 6th was my final recon surgery to replace tissue expanders with silicone.
With regards to your chemo treatment and questions you might have, it was really helpful for me to search in this forum my chemo drug names and even just reading posts with the tag 'Chemo" which you can find in the discussions section (to the right). You might find a lot of your questions answered there by ladies who have gone through treatment.
I just want to say we are all here for you and wish you all the best with the challenges ahead. You seem to have a very good outlook in life and your positivity will help you a lot. I love how you said consider the universe was clearing out the 'debris' in my life. That is a very good analogy! Remember this is a Marathon, not a sprint. Focus on today and what needs doing today only, do not worry about the next week, month or anything you are not dealing with right now, because you need to retain your emotional wellbeing and focus for the present. The rest can go on a virtual shelve until it needs doing. You can do this! We are all cheering you on x
