@laurie123 if you are interested my appointment with my onc was interesting. She has said I have to stop Tamoxifen for three weeks to see if the erratic behaviour and tears etc get any less. As I am suffering insomnia as well she thinks perhaps its the tablets plus that making my anxiety and tears and flat feeling all feel worse. She also said of course menopause could also be a huge part. So we are I guess doing a process of elimination to see what is causing what because I just feel a huge hot mess and have no idea what is causing what, I only know how I feel most days. I panicked in the first instance at stopping the tablets but it is only three weeks. She then said I may start back on half only.
The only other thing mentioned was perhaps to take a mild antidepressant to counter act the Tamoxifen but at this point I politely declined.
I hope you have been feeling better xx
