Dear Estherch, Sorry; this is 'normal' . I'm sure other network members will reply, and you will hear that everyone reacts differently to their chemo. Many people find there is a pattern that emerges for them - keep a chemo diary. You might get your worst days for some of your side effects, and then things pick up. Yuck and scary for you to feel exhausted and emotional when you are usually bouncy. Many ladies recommend the BCNA hotline to talk about concerns. Some things you should get medical help for straight away. Have you got lots of info from your clinic? Do you have a breast care nurse you can talk to? Posting on this network is really good to share concerns and get lots of virtual hugs! Hope you feel better soon, and best wishes from jennyss
