@Caroline71 So sorry to hear of your sudden diagnosis but you have found a bunch a new friends here who will support you, guide you & give you the best personal advice possible. No judgement here & you can vent all you like!
I lost my mum when she was 46 y.o. to ovarian cancer & although I cant even remember her as I was only 3 when she died, my first thoughts were of her when I was diagnosed. I can only imagine you were feeling the same about your dad. Try not to compare as treatments progress so quickly these days it will probably be different to your dad's.
The emotions, blurr of the past days must be overwhelming with appts to be made, decisions to be made & you left worrying about the What if's?? So much great advice so far that we give to the "newbies" but I will second a lot that has been given.
Get a breast care nurse ASAP. Your new best friend. I can ask mine anything, stupid questions or otherwise & she will tell me what I should do unlike some medical professionals who will guide you to make your own decisions. Sometimes you just want black & white with no grey & for someone to make decisions for you!! Breast care Nurses are trained & can give you the best advice either personally, email or by phone.
Get brochures & info from BCNA & Cancer Council websites & also the doctors waiting room. Info is power & info from those resources are more appropriate than Dr Google!
Take hubbie/friend/family to every appt for an extra set of ears as you will probably only hear half of it. Before you go, write down all your question & there are no silly questions if they are on your mind. Take notes or record the appointment.
It's hard, but try not to overthink things...easier said than done. The goal posts change constantly so there is no use worrying over something that might not eventuate. Stress fuels cancer so dont over feed it with unnecessary worry. I worried about everything, as we all do. What surgery/treatment to have etc & most of what I worried about, I didnt even end up having so that was a waste of my strength! Focus on what you do know & the next step, not what may happen.
Be kind to yourself & take all offers of help/food etc. Look after yourself, breath & stay strong. We are all here with you. love & hugs xx
