Hi @Loo - welcome to the forum - ask away any questions you may have - there is always someone who will have experienced it, or have some honest advice to help you thru it.
We've all had to pull our big girls pants on at some stage ..... it is such a whirlwind, the first 3-4 weeks after finding the lump ,..... the dread & devastation of realising that it is BC ..... then the surgery & others treatments as well .... You can do this.
I am guessing you've had your pathology resultS & hope they are OK. Yes, Family & buddies will continue to ask if you are 'OK' - and it is OK to say that you are feeling a bit fragile at the moment! We all try & shield everyone from 'their shock' which can take a bit out of YOU! No doubt, some will also assume that now you've had your surgery & about to start the rest of your active treatment that all is a 'good'. It all just takes time, to recover physically AND mentally.
It really is as much a mental struggle as much as a physical one. If you feel that you are struggling, don't be afraid to ask your Breast Care Nurse or Surgeon's office about accessing a psychologist to help you get thru it. Don't let it become a stumbling block.
Try not to use Dr google too much - a lot of the info is 10-20 years old & not necessarily relevant to current treatment methods - or to your particular BC.
Take care & all the best with your Onc's appointment next week xxx Big hugs coming your way xx
