^ some of these are definitely less helpful than others but i find anything having to do with focusing on how things feel or look helps.
and maybe try constantly reminding yourself that you are the one in control, say it out loud if that's what you prefer. you're mind quite literally has a mind of it's own. maybe look up things that debunk the delusion you may be having is possible. like reading about god and origins of religion and such. i would say be careful when doing this though cause some things you read may very well fuel ur delusions. such as the "god is in all of us" preaches.
but if u need some words of encouragement or debunking here (feel free to skip if people denying ur delusions trigger you, i don't know what state ur in right now so im just being cautious)
you are in control. god isn't in ur head and he cannot hear every single thing you are thinking. you're mind is a safe haven where only you know what's going on, nobody else can violate the privacy of ur own thoughts. neither can they judge whatever you may be thinking if you havent said anything aloud. i don't know what ur beliefs may be but i can assure u that god probably isnt going to be constantly in ur mind while there are millions of other people he may or may not be listening to.
i hope you can find a way to sooth ur delusions though. sending much love <3
