Advise needed please....

Hi, I'm not  in a very good place today, saw the oncologist yesterday. So I'm hvg 3 cycles of EC chemo, then 3 cycles of docetaxel and herceptin, and herceptin carries on for further 16 sessions (48 weeks) and radiotherapy starts after second lot of chemo for 3 weeks daily, then tamoxifen. I'm really struggling taking it all in. They told me that I should take 18 weeks off work as it's a strong dose of chemo and I won't feel up to much! Can anyone who's had this EC or D tell me anything about them from experience? ATM I just want to run away....... Hugs xxxx.
