I would email you but since you have no contact information on your profile I will just say I strongly urge you to seek medical advice, and maybe seek out a pastor at a mainstream church to discuss your situation.

I knew someone who nearly died and who held very similar non-mainstream medical and non-mainstream religious beliefs.

When they were in so much pain they couldn’t even stand up they finally agreed to be taken to a hospital where they lay on the floor of the emergency department. It turns out they had a near fatal infection in the spine, which was easily cured by antibiotics (after months of agony) and the suffering reduced by painkillers.

It’s a matter of personal belief but I don’t think there is any higher purpose to real suffering (suffering caused by illness or by other people).

I also don’t believe that you stand to lose or compromise your faith in any way by accepting medical treatment.
