I was diagnosed in January with hormone positive IDC. I'm 40 yo, my first mammogram. I had a lumpectomy, radiation, and just started Tamoxifen this week. Physically I'm fine. Mentally I'm exhausted and can cry at the drop of a hat. Get plenty of rest, drink lots of water, my oncologist recommended Ginseng to help with fatigue. I'm just starting it as well. There's a Mayo clinic study you can Google if you're interested. You'll do great! Listen to your body, that's the hardest part. Slow down and take care of you.
