More scared now than before starting chemo

I haven't been on Zoladex but was on tamoxifen if that helps lol....I was on it for one year until it started to make me nervous thinking about the side effects and long term effects. The only advice I can give you is to be as informed as you can be, ask the questions that are on your mind. If you don't get the answers go to another doctor. And do what is best for you. 
I ended up going to a psychologist which you can access through either the Cancer Council or your breast care nurse, after what we have gone through no wonder we get the hibbee gibbees! Good luck x
