Am I experiencing possession or a mental illness with scary thoughts?

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?

I feel that this post could be triggering so please approach with caution! I’ve been having a lot of intrusive thoughts about the devil getting sent my intrusive thoughts and then making them come true. This has also led some of my intrusive thoughts to include that they’re for him. It’s really scary. I’m not even religious, but it’s really hard to shake. Does anyone have any advice or comfort? Thanks <3

Lately I’ve been having demonic thoughts, possession thoughts and just nasty thoughts about my soul and thoughts about my heart and the devil. Is that normal in OCD? I would never want that or say that! But recently been having false memory OCD and I’m scared what if I’ve said those thoughts out loud!! I’m always trying to say God & Jesus owns my heart & soul but I’m scared what I’ve I accidentally said the enemy instead! These thoughts cause so much discomfort! Please any advice? Does anyone else go through this?
