I say almost nothing because it’s not as if everything is all rainbow-farting unicorns. There are symptoms you have every day that are so minor you forget to mention them when the major ones are happening. Or that as a symptom itself, ie forgetting things or being generally confused, also known as brain fog or chemo brain.
Are things – oh, I’m sorry, people – like you allowed to hurt? Doesn’t admitting to your pain diminish you? Doesn’t it make you weak?
