Hi Rachel,
If everything I have been reading about w/d and a/r is true, looks like you are more than half way there in terms of healing. Do you have a good support system in place?
Terrible that your GP's "book" said that it is impossible that the meds caused your new condition after starting them, seems they have incorrect info. Here in the US, I have actually spoken to medical staff that acknowledge these meds cause serious problems (i.e. depression, etc).
Sorry you are stressing out with the health anxiety. Some people say the best way to put that fear to rest is to simply go get checked out. What type of cancer do worry over?
Welcome
