Hi @laurie123, I agree with comments above. I was in tamoxifen for 18 months post chemo and radium. I did get counselling during treatment. Tamoxifen surprised me with the side effects of fatigue, breathless and feeling flat. I would talk to your oncologist about it. However for me the fatigue and breathlessness got out of control and also impacted my mood. My oncologist gave me a 6 wk break and started me on Letrozole. Omg what a difference. It isn't perfect as I have some bone issues but switching for me has been a winner. I think the key here is talking to your gp and or oncologist and perhaps talking to a counsellor too. Keep advocating for yourself to get well. Best wishes
