You will make it! Somehow we all get through it. Take good care of yourself now. Embrace the nap. Most importantly, it's OK not to feel good now. You are going through a lot. I had to do 8 rounds of chemo. After the third one was the worst for me as far as wondering if I would get through. It seemed so far away but after I went the next time, I was half way done. Then, even though I was getting sicker with increased side effects, knowing I was getting closer and closer to being done made me feel better.
I am 3.5 months out from chemo and I feel fantastic. I would say it took a good month before I started to feel a little better and then I would feel better and better every day after that. I still have hot flashes and numbness in my feet and hands but my oncologist told me to give it a good 6-8 months before all the side effects are gone.
We are all cheering you on. You will get through this!
