@ConcreteLunch and @eladnarra, my wife is also a breast cancer survivor. She was 40 when she was diagnosed. She’s alive, and cancer free, but she’s got chemo brain. It’s harder for her to focus, even on stuff that interests her. It’s harder for her to make herself do things she knows she should do.
And, given that she had her ovaries removed as part of her treatment because she was genetically predisposed for ovarian cancer, she’s gone through other changes that I won’t discuss here. It changed her life, and not for the better. I live with it because it’s better than living without her, but I remember the woman she had been before her diagnosis and I miss her. I just don’t let that stop me from loving the woman she is now.
