Having had more than one occasion in hospital where I have been obnoxiously prayed for and at, and, when objecting, told that there was no point and no hope to my life without Jesus...I'm in an absolute froth about this.

You are already asked about religion when you're in hospital...if you have a particular faith, if you want a chaplain or any other religious type to come and visit you. If you ask, they'll find you someone to do all the spiritual handholding you want. But, it's not the job of medical staff, and it shouldn't be.
