My advice is to google away--most of us do it anyway. some sites including this one have their own bias
I do agree that this time you describe is one of the most difficult--but it is a diagnosis of cancer and potentially life threatening so give yourself room to feel shocked, upset, anxious and then in time there is also room for positive outlook and that for most women it is treatable
In my early days--speaking 6 months out! --i found some of the messages that reflected others experiences were not my mine--you wouldnt know i had surgery, i only missed probably 4 weeks work and two
weeks of that was annual leave, i didnt have chemotherapy, i wasnt offered mascetomies, elected mascetomies etc...life was pretty much the same with a anxiety thrown in, more rest, less alcohol, more excercise...side effects for tamoxfin have been minimal....
there are a range of possibllities and experiences ---this initial phase does pass and those intense feelings..in my experiences get better
best wishes
