Mid 40s male...I've found the last few years "s-ymp-toms" I may of had years ago I didn't think twice about but now they can cause a-n-xiety. Has this occured with you?

It's late at night, I couldnt sleep. Not sure if I have HA but I'd rather it than whatever this is. I thought for a my mother was replaced by an imposter for half an hour, which made me so terrified I cried. And I still suspect school administration may be using my roommate to track me bc of teachers act. Latter has been happening at least a week possibly even before i dont remeber. I am sure it's been at least a week, while first one happened this night. I have read that reading symptoms may cause them to manifest due to anxiety but both of them happened before reading about symptoms.

BUT two days ago I was looking at cluster A disorders bc of intellectual curiosity. While I have some very very superficial symptoms which can be easily explained by other Neurodivergencies (such as ADHD, which I'm officially diagnosed with), I didnt give it much thought until now. The second part of the question is about the having superficial symptoms part. I read in this subreddit about people starting to have the symptoms upon hearing about them but what I experience is different, in which I can pick and choose the ones I am currently and remember experiencing and recontextualize my own experiences in light of them. I wonder if it can be HA? Idk if I should be posting in this subreddit (which I discovered just rn) for reassurence since I am not even sure if I have HA but this is the only place I can look for comfort.

does anybody know if your subconsciousness from health anxiety causes chest pounding and faster heartbeat along with chest pain?

from my understanding and in most of my experience, health anxiety often latches onto irrational things that have no evidence of actually being true. but what do you do when you do have a health issue, but the anxiety has blown it out of proportion? i've dealt with every spiral health anxiety has thrown me, except for this one.

TW talk of tinnitus and ear-related things:

a year ago i got stress induced tinnitus which turned chronic. it wasn't from hearing loss. i dealt with it through therapy and it's gotten heaps better. but since then, i've become utterly obsessed with my ears, specifically the fear of getting hearing loss. the anxiety caused a few other ear symptoms too, like hyperacusis and distorted hearing (which went away) and middle ear fluttering. i am pretty sure i have tensor-tympani syndrome (from stress) and am looking into specialised treatment for that.

but my pre-existing anxiety has made me convinced that any sensation in my ears, such as this persistent fullness that comes and goes, means i have hearing loss. i'm terrified of loud sound and block my ears all the time. i also have tmjd (jaw issues) that i suspect cause some of my ear symptoms like the fullness and popping.

my point is though that the anxiety surrounding this has become inescapable, and the things that usually help me out of overthinking and health anxiety spirals aren't helping me for this, since there is some realistic/physical backing to my symptoms. since my tinnitus onset a year ago, i've done 3 hearing tests, been to the ENT 3 times, seen a neurologist, seen my psychiatrist, been seeing my psychologist, and worked with an audiologist/CBT therapist for 6 months. every single specialist has concluded that my ears are perfectly healthy and it is anxiety that is perpetuating my symptoms. yet i'm still convinced that this fullness sensation means i'm losing my hearing. 6 weeks ago i fully convinced myself i had hearing loss to the point where i could've sworn sounds were quieter in my left ear. hearing test indicated 10/10 hearing. i got over it for a few weeks and the sensation went away, but now it's back and im back at square one. usually i have decent insight and can rationalise when im calm about my anxiety. but i haven't been able to do this this time. i'm really convinced theres something wrong despite all the evidence pointing to nothing being wrong.

i genuinely don't know how to help myself out of this one and was hoping anyone had experience or advice they could share.
