Hello, sorry you've got that news, and not good that it was delivered this way. Can I ask which hospital?
We would need more details on your diagnosis and treatment options before we can give you useful things to think about which are relevant to your case. It's useful to fill in your bio so people can read that before replying.
You'll get lots of advice here, but another thing I would suggest is to look for a local support group, because they'll know your hospital, clinicians, and how treatments are offered, which can be very useful too. https://prostatecanceruk.org/get-support/find-local-support
