This is a very tricky situation for you and I sympathise with your concern for your mother. You cannot allow yourself to feel guilt over her making herself ill because you don’t believe what she does. I think the best thing you can do is try to keep her calm and try to avoid the subject of faith. It’s an unfortunate fact of life that some parents cannot accept their children grow into adults with independence in all things, including thought and belief. I hope her health improves and that an understanding between the two of you that her belief in god cannot be imposed on you.

No-one is responsible for the illnesses of other family member UNLESS they have deliberately set about to cause them by either subjecting them to physical harm, poisoning them or by any other means that can be classified as Illegal/Unlawful.
So, @Albert_Camus, shake that blame from your shoulders since your mother, etc, IS playing a very well utilized and well known trick of putting a Guilt Trip onto you in an attempt to drag you back to believing in God/Jesus and all that utter bullshit and garbage she clings to.
DO NOT allow yourself to yield to her completely underhanded methods of persuasion and duress PLEASE.

Best wishes to your mother. May she stop stressing herself out about the views of her enlightened child.

Well to start I hope your mom stays well. But then think about the vindictive God she must believe in that feels he will punish her for your non-belief. My mother was a devout Catholic and I assume so was my dad, he played the part anyhow. I will say I'm thankful but I never was aware of them playing any kind of blame game, stay strong.

Christ is on the cross. His blood is dripping. Quick! Get another nail! His head is slipping!

Your mother didn’t get sick because of your beliefs. She got sick because of her thoughts, actions, and responses to your beliefs. If her god is powerful and benevolent enough to make her okay again, he could make her stable right now, but what? Chooses not to? Not so benevolent, is he?

Yes. I see the giant pink bunnies too.

yup, sounds like Catholicism alright. I mean are they the best at casting blame or what? Fwiw that has nothing to do with Christianity at all, not that most xtians do either i guess. On the other hand, Catholics are where one usually finds themselves going to if they are down and out! Weird, huh

Sad situation

People will go to extreme lengths to force their beliefs onto others, even to the point of making themselves ill. It can be difficult to keep yourself from feeling guilty but you are not the cause of their symptoms, they are.

I know people that act the same exact way. As long as you come out of this knowing that these people have been indoctrinated in these beliefs and that they believe what they're doing is good it's a decent framework to begin the process of getting them to think more critically. Hopefully your mother will come around in the future, but if not at least you know the truth.

She is doing it to herself, and trying to shame (coerce) you into adopting her beliefs. We are not responsible for someone else's choice to behave as they do. We can deeply regret that behavior, but we are not responsible for it.

Same story for every atheist

I'd walk away forever.

I never told my mother I didn’t believe in god as I knew she would be devastated. She suspected though.

My mum is the same way when ever I say something like what is the point of prayers. Although I get the you sound ignorant comments which just makes me keep quiet because those kinds of comments make my self esteem take a nose dive. But I don’t give up on my beliefs no matter what

Seems they always thank god(s) for what ever happened to them, when some how they survived what ever befell them in the first place!!!

When will these duped souls realize that it was there god(s) who put them or made the situation that they were in or recovering from according to their demented delusional beliefs!!!

When your beliefs in god(s) is so much greater than the sanity you were born with!!!
