I'm similar to you as we'll. I'm 42 with 2 teenage children. I was diagnosed at 40 Though and have finished treatment. The thought if chemo is so scary. But it's doable. I didn't work during treatment. I did have node involvement and needed TAC chemo. I felt bad for the first week and completely normal the 2 weeks after that. With more treatment I had the bad week got longer and after the 6th round it took all 3 weeks to start feeling better. The hair went after day 18 and I cried more about losing hair than I did my breast. I wore scarfs and enjoyed styling them in many different ways. I got a whole lot of ideas from You Tube and I got comments all the time. Good luck with your treatment. I hope you have minimal side effects. 1 tip, eat and sleep whenever you can.
