Bugger! Sorry to see you here under these circumstances, @eightdays ..... even as a mental health professional - this is still a kick in the guts, so we all feel for you.
You CAN do this again .... I am guessing your pathology has not shown anything in your nodes .... just that your surgeon would like bigger margins?
Where abouts are you (Town/city) as possibly chatting with other members over a coffee may be helpful?
It is 2 years today since I had my own surgery for Invasive Lobular - with some of my own margins pretty thin ..... so far, so good.
Would you consider not having a recon if it is going to be so tricky? One less surgery to face both for you and the kids? You will be no lesser person .... but definitely braver xx
Deep breaths, take one day at a time, one hour at a time, if necessary ..... these are things you would have told many patients in the past ..... difficult tho it may be, to take your own advice! :(
Take care, know that we are thinking of you and the best outcome for you xxx
