Hi penny, I too have been on Zoladex since Feb last year and like John we seem to be mirroring the side effects.
I cannot add much to help as it has mostly been said by the others, the tearful bit can be embarrassing depending on where I am at the time especially when the people around me do not know the reasons why. My wife usually steps in to explain, bless her.
Once your dad has spoken with the oncologist and there is a treatment plan you will know more and if you need to ask more questions on this site there will be plenty of us to help you understand what you have been told.
Have you downloaded the "toolkit " from this site yet? You can also get one posted by calling the number here as well look through publications.
When your dad goes for his appointment it will be very helpful for your mum or yourself to go with him to be able to take in what he is told. It is so easy to miss something and if you have questions to ask write them down, also write down any details provided like PSA result, Gleason score, staging and anything else given.
Best wishes for his appointment
Chris/Woody
