Prostate cancer stage y

Well I got my PSA reading for September,every 3 months I have to have a blood test just to keep track & inform my GP my PSA is 692

I will need to ask my GP to book a full body scan so they can see how far my prostate cancer has invaded my body

Death comes easy if you've had a great life which I have had so I just accepted my cancer diagnosis from day one,and after reading extensively I realized I had no chance of survival with:

Initial PSA in 2019 of 109 that means it advanced already invaded all my body tissues & the Gleason 9 indicates my Cancer is very aggressive.

I am a practical person so I im fascinated about how death will take me & how I will feel about it will I be aware etc etc 

I know my outlook is totally different from most people but I've never been afraid of anything in my life so why should I be scared of dying?

I'm 61y old I may see 62 but will not see my 63rd birthday the thing which bugs me is the state will get all my state pension that I have worked for from 16 years old!
