Dear Michellebella,
i know what you are going though I have been there (living this since 15/6/2015). It does seem like a long road in front of you but as the very wise women have said above take it one step at a time. There might be complications and setbacks along the way but you will get though it, time does pass ( sometimes very slowly!). The shock and anxiety are the worst, I was prescribed sleeping tablets which I could not do with out when going though treatment. Ask for help, sometimes you might have to shout for help! I could not have lived with out my McGrath nurse or this website, invaluable.
It is a process, chemo is hell but you will survive it (mostly intact) and radio is a breeze (in comparison), you just have to expose your boobs to a few technicians every day for a few weeks. Most hospitals have accommodation that patients can stay in, I stayed with friends which was great as I live 2:30 hours from cancer clinic. I enrolled in an online course during this time to fill the hours and shopped ( this was only for therapy;-)).
You will get yourself a team of doctors and supporters to help you though. Best of luck and you can ask any questions here or just rant.
take it slow and remember to breath!
Kim
