That is scrupulous. Keep in mind that the bread which hosts are made from is designed with ingredients and shape for the least possibility of crumbling.
What others suggest, receiving on the tongue, you might also try. That’s how I receive, and after so many years in the hand it felt awkward just once or twice. But now receiving on the tongue seems so much easier. I don’t have to do anything except open my mouth. I can trust the priest has enough expert experience that all will go smoothly.
As for the Blood, we have the Chalice but I do not take it because it’s redundant and then I need not worry about spilling any.
Finally, scrupulousity, if a person really does have it, is an old religious term for what is actually a treatable medical disorder. There is no shame in this and no flaw in the person’s character or psychology. They just have a bit of “wiring” in the brain that can cause obsessive and/or compulsive behavior.
Because God has provided us with the miracle of scientific treatments for “OCD” or similar problems, it is a good idea to talk to a doctor or psychiatrist about a diagnosis.
I recommend this to anyone on this forum who defines him/herself as “scrupulous” or if your family says you are obsessing about tiny matters repeatedly. Ask your doctor if you might have this disorder.
Again, it is nothing that is your fault, it is not a moral weakness, it is not a psychological problem…it’s none of those. It’s a medical disorder and should be handled as such, for your own comfort.
