A problem with my mind 'intentionally attacking' me - #10581

I'll explain, i guess i should start with my history of this in terms of anything possibly related to my current problem: an fyi, im a 49 year old male, ok, here's some examples of earlier issues i sorta suffered from, and then to the more serious issue im suffering from in present day: Back in the 1990s through the 2000s, troubling thoughts would occasionally occur to me, like, 'what if i get a song stuck in my head, and it just would continue replaying in my head? that would be not good', and on another occasion 'what if i started to have to swallow, nonstop, endlessly' and on another occasion 'what if i began to itch, and be itchy, and have to constantly itch' now when i would have these kinds of troubling thoughts, the symptoms of each one would actually manifest, and i'd experience the troubling thing i worried and thought about happening, but they all eventually faded away when i realized they were all just in my head and only powered by my obsessive worry about them a few years forward from those, in the 2010s, a couple of incidents happened, while i was on the internet, one happened on a chat website, where you talk to random strangers and you or they can next the person they're talking to, or not and continue the chat, i seemed to notice ppl would next me a number of times in a row at certain times, looking back, i see that as coincidence, and streaky things do happen on occasion, odds-wise, but at the time i viewed it as suspicious, impossible, beyond mere coincidence, and since all those ppl were just unrelated strangers to themselves and me, it sorta crossed my mind that the only possible reason for that streak and trend was that i was being messed with, and/or i was in hell, but i figured maybe not, and actually brushed it aside and chalked it up as just coincidence. a couple of years after that, and this was march of 2014, this was when the genesis of my current issue began, i was on the internet, on instagram, where you can browse random people's profiles, and i seemed to notice a trend, where the people who i most wanted to look at their profile, always had their profile set to private, and the people i was slightly less interested in checking their profile, always had their profiles set to public, my reaction to this was that i was somehow being messed with and targeted, and that the only way this trend was realistically possible was due to some supernatural reason, or i was in hell, this lead to me to eventually think, later that day in fact, that if THAT trend happened to me, due to some supernatural force doing it, or because im in hell, then other things may be done to me or against me, because that's how being supernaturally messed with, or being in hell works, being attacked/tormented, in various ways, so my mind began thinking up what other ways i was going to be messed with/attacked/tormented, and it occurred to me that god, or the devil, or whoever was doing that to me, could and would use my mind to try to torment/attack/sabotage me, in various ways, by, without my consent or control, thinking up ways to do those things, with my mind, by highjacking my thoughts etc, and causing chaos and torment etc, and as soon as that possibility occured to me, it did start to actually happen, due to my mind expecting and anticipating those things to happen, my mind started doing those things, now that alllasted a couple of weeks, and through self-analysis and thinking, realized that i wasnt in hell,or anything, that i was just being nonsensical and unrealistic, and once that occurred to me, my symptoms, of my mind attacking/sabotaging me, stopped, once i realized there was no actual threat or anything being done to me, but, eventualy i began to think about other ways and reasons that could possibly explain the instagram trend, and over the next 12 years 2014-2026, there's been many different possibilities that i have thought of, and all have amounted to me thinking my mind was intentionally attacking me, all of which allegedly explained away why that instagram trend happened here's some examples: - the supernatural theory - the in hell theory - the god punishing me thoery - aliens programmed my mind theory - i was just a dream theory - my subconcious is trying to mess with me theory and in all those cases, when i believed those things were a possibility, my mind would continually try to think up ways to sabotage/torment me, out of fear and anticipation of those things, but in each of those cases, once i realized those things werent actually happening, my mind stopped intentionally attacking me, because i realized that there was no actual threat or anything happening but, in these more recent years, my theories and concerns have gotten more realistic and sophisticated, for example - i had a theory that schizophrenia was intentionally taking over my mind to attack me with it, but after researching schziophrenia, i ruled that out, that isnt exactly how schizophrenia works. my current theory i have is that ocd is causing my mind to intentionally attack me now for the past 12 years, i've had a history of believing something(s) was causing my mind to intentionally attack me, and had to suffer through those times, and the cure each time has been a realization that those theories were not true, and my mind ceased attacking me. but, this latest theory about ocd has me back in that same cycle, it's the latest theory that i believe is the cause of my mind intentionally attacking me, and im no doctor, and i need help figuring this out, is this just another false theory? i hope i explained things well enough
