I hope it's ok to post here as a daughter and not my dad..

I'm new here and  a little nervous, I have been reading some of the posts and they have been brining me slight reassurance. There are some really brave and incredible people on here.

My dad 2 months ago has been diagnosed with stage 4 prostate cancer. His PSA was 282 and he had never been tested before. He is 71, Gleason 9, spread to distant Lymph nodes, 1 in between the lungs, a couple in his stomach and pelvic area, with a T4 tumour. 

He is a semi healthy 71 year old (he has asbestosis in the lungs)

He is such a happy, active full of life man, he is a plumber and still works everyday and refuses to retire. My dad is my world and best friend, this has hit me and turned my world upside down and I'm struggling - more than he is - I don't massively think he understands what's going on, not sure if ignorance is bliss sometimes. 

He has been put on zoladex and apalutamide, and is awaiting radiotherapy. On his first month of zoladex his psa has dropped to 12.8 (not sure if that's good or not) 

So yes that's his journey so far, I guess im just looking for any advice on treatment, and how to handle things better as I'm not coping great, I'm scared of how long he has left as everything I have read on google isn't great, maybe im searching for some help.

Thank you x
