You can clearly engage in an intelligent argument so I don't know if your symptoms are exaggerated

I also do not see what faith has to do with this. Being in this forum that long you knew that kind of post would result in many jumping in trying to save you by faith and getting a lot of attention

I suggest you try other things, if your symptoms are actually how you describe them then they seem too acute to be heavy metal toxicity. You suggested it might be early onset schizophrenia (which apparently there isn't much known about it) or other brain problems that would not just show up in a MRI or test. Maybe Cognitive behavioral therapy or specialists that can study your symptoms and not just do a test to check for a tumor and send you home when nothing shows up

While I know to the religious people are trying to help, if I was that sick and didn't share your beliefs, many of those posts would feel like a slap in the face.
