Hi Jussy
Sorry to hear that.
In fact you were doing so well to the Chemo. This stage has gone. It's worth to reward yourself, you've really done a great job.
I can see that the chemo process purposely shrink ed your cancer cell so could ready for the surgery.
Please be brave, it may be a long way though, but it's good you come to this Web. We could share our experience and feeling. We all could support each other.
Yes, we are a patient, but it will gone, please don't let it knock you down. Sometimes we were sick, and that's it.
Dont let it control your thoughts, stay positive and happy. There must be something you could do to make you happy, maybe a movie, or an exercise.
Stay well yourself.
No doubt the Tamoxifen do affect your mood, especially it stop the estrogen, just like forcing us to menopause stage. I believed even without cancer, for those women in menopause stage would suffered from insomnia, bad temper, rough skin, etc. So keep relax and deep breathe, find interesting things to do and enjoy life. (This is I learn from this cancer)
Take care (hugging)
