Hi Kerry,
I finished my chemo six weeks ago and am now on to radiation. I was also shocked at how it knocked me around. I am 43 and I was planning to keep working through chemo!!! My doctor had said some women do this and are ok - how silly was I to listen! My chemos knocked me out for about 10 days each time. You just have to go with the flow and hopefully your family will understand. My kids are teens and they were pretty good through the whole experience. Hopefully your husband can explain things to your girls in a way they can understand - it's really hard I know. Best of luck with it all and be kind to yourself.
Mel
