Why am I fearing psychosis with intrusive thoughts despite being an atheist?

Hello, I have hypochondria, gad, ptsd, and panic disorder. For the past 5 months I have been in a deep episode of what I’m hoping is just hypochondria where I’ve fully convinced myself I’m psychotic/developing schizophrenia. This theme has become so debilitating I lost my job and was completely bed bound for a while. Anyway, I have the extreme fear of developing delusions and hallucinations, so I’m constantly on the look out for symptoms like that. For whatever reason I have become extremely sensitive and afraid of anything demonic or horror related, I literally used to be a horror junkie, listen to Marilyn Manson etc. I am literally an atheist, I don’t even believe in the devil or superstitious things like this, but for some reason I have started getting extremely fear inducing demonic type intrusive thoughts, like one night I had the terrifying thought “what if my wife is possessed by a demon and isn’t really my wife” this thought scared the fuck out of me and actually changed my behavior towards my wife and gave me a panic attack, the fear of that later passed, but the uneasy feeling still linger. I’ve been getting all sorts of terrible demonic type intrusive thoughts like that about everybody and random places and even objects and they cause a panic attack everytime I get them, it used to be a panic attack about struggling to fight the urge to believe these thoughts but now I feel like it’s gotten to the point where it just straight up feels like it’s happening and I’m afraid for real and not even questioning the thoughts anymore. I’ve completely stopped listening to any music that references the devil or any type of media that may have dark references, to avoid getting these types of thoughts. When I am not anxious and I take my anxiety medicine (clonazepam) I can laugh these thoughts off and confidently shrug them off as ridiculous, but other times it feels real!Why is this happening to me? Keep in mind I am a literal atheist and do not believe in superstitious things like this, why am I suddenly afraid of things like this? And better yet why do they scare me and “feel real” if I don’t believe them. I feel like I’m fighting for my sanity every single day. I literally dread the anticipation of getting these thoughts. These strange new fears about demonic shit is only solidifying my root fear that I am developing psychosis. Can anyone please help me?

To start off, yes I have a therapist, yes I have a psychiatrist and so far I am only diagnosed with ptsd, ocd, gad, hypochondriasis, and panic disorder. So for the past 5 months I’ve been dealing with a terrible ocd/hypochondria theme where I have COMPLETELY convinced myself I am in the beginning stages of schizophrenia or some other related horrific psychotic disorder. Ive read way too much on common delusions, symptoms, hallucinations, personal stories, Reddit stories etc. Anyway, for some reason my ocd has really latched on to the common symptom schizophrenics have which are religious delusions, at least I hope it’s just my ocd and not actually schizophrenia. Everyday I get these terrible existential/demonic “delusional thoughts”. Like “what if my wife is a demon” “what if my cat is a demon” “this song has demonic energy” “the face that person made was demonic” “this house has negative demonic energy” “what if you are possessed” “what if these ugly brown mushrooms growing in your yard are a sign of demonic energy”, shit like that. Literally everything I look at now has some sort of “negative energy” or feels eerie or “demonic”, everything I look at always has to have some sort of malicious intent or negative undertone, I can’t watch anything on YouTube anymore, I can’t listen to my favorite bands anymore like Black Sabbath, Iron Maiden etc, these thoughts have made me become so avoidant of dark things and even normal light hearted things! Now first off, I am a literal atheist, I am a complete skeptic, I have never ever been superstitious. I was a huge Marilyn Manson fan in my teens, I’m a horror movie junkie( or at least I used to be before this theme took over), i literally have shirts with pentagrams and upside down crosses etc. why has my ocd suddenly branched off into this religious ocd/delusional thinking? Is this maybe a dp/dr thing too? It literally feels like I am in a horror movie, when I’m really REALLY spiraling and ruminating hard, it feels like I’m in another world filled with pure DREAD and horror.I know for sure that every single one of these thoughts and feelings are untrue and very unlikely when I’m not as panicked but when I’m in deep rumination/obsession it seriously makes me question what I believe. I do not believe any of these thoughts at all when I’m calm! Yet the fear they create and the vibes that accompany them make it feel real. When I’m in full blown panic and start to spiral really bad sometimes I feel like I almost believe these thoughts, and feel paranoid almost, when the anxiety and fear passes though I can have a brief moment of clarity where I can laugh these thoughts off and almost be myself again, but it’s very short lived before these thoughts start creeping back up. The content of the thoughts is scaring me but the fact that I’m even having these types of thoughts and fears in the first place is scaring me even more because it is reinforcing my fears that I am becoming schizophrenic/psychotic. Why have I suddenly become like this? I can’t enjoy anything anymore without getting these awful awful thoughts. Has anyone ever experienced anything like this?

Does anybody else’s intrusive thoughts come in the form of “delusional thoughts”? I’ve been in a terrible episode of hypochondria or ocd for the past 6 months where I have FULLY convinced myself I am developing schizophrenia, it started with becoming really easily overstimulated and not being able to concentrate and now it has spiraled out of control to where I am constantly getting intrusive thoughts center around demonic stuff, which i have never ever believed before, I have always been skeptic. But now i get these thoughts all the time like “what if this song has hidden demonic meanings?” “What if your wife is a demon” “what if nobody is real and your just in hell” “what if this political figure if just being controlled by the devil”, the typical kind of delusional thoughts you would expect from a schizophrenic. Not only does the fact that I’m even having these thoughts in the first place scare the life out of me, but I have to constantly battle with these thoughts in my head if I believe them or not. I feel like I have to constantly hold myself back from fully going off the deep end, I feel like I have to constantly disprove these thoughts and stop myself from believing them, but they feel so real and it’s scaring me so much. One part of me is like “why can’t we just stop worrying about this, this is delusional” and another part of me is like “what if I actually do need to worry about if these things are true or not, they FEEL true” and I’m just like “wtffff I shouldn’t have to worry about if things like this are true at all in the first Place!” I feel like I have fully lost my mind, and in no time I’m going to lost this little bit of insight I have. Btw: yes I am seeing 2 therapists and a psychiatrist and all of them do not believe I am developing schizophrenia.
