Health OCD Anaphylactic Shock

This should be common sense, but unfortunately I stumble down these rabbit holes and subreddits because I have a complicated health problem, and am trying to seek a similar community. I have sought out medical advice with no real conclusion and ocd anxiety makes things worse so I guess this is a form of compulsion? I’m not exactly sure anymore. Anyways, I had a strange experience last night where I had a bit of swelling and discomfort in my mouth and fingers. I took an antihistamine just in case, and the issue resolved itself. I posted in a histamine intolerance subreddit asking if anyone has experienced similar as there was no known trigger. Well, someone told me it was anaphylaxis and that I had to be more careful with what I ate. Anaphylaxis is already a trigger of mine, and although I know logically it couldn’t have been, the opinion of another person feels like confirmation. I am now afraid to eat or drink because of it. I am unsure if posting on subreddits was a compulsion now but please be careful with anything like that. It can make things so much worse.

It started when I became an adult, and started receiving my mental health diagnosis. I hyper fixated on each and every action I did and how it could be related to my diagnosis’s. It then lead to fixation to my physical health — making appointments and seeing every specialist I can to rule out every possibility. I currently have been suffering with obstructive sleep. I woke up the past few days with severe pain from the lack of sleep whilst believing I was oversleeping. Luckily my fit watch tracks my sleep cycle and it turns out I am not receiving any sleep. I had an extreme panic attack — bursting into tears on the phone with my mom wondering what this case might be. She told me it could be sleep apnea and that a simple sleep study could figure this out. However, knowing my family history I made appointments to every specialist I can to make sure it is nothing serious. The unknown of health can be scary to me. Watching my mother suffer with her physical health chronically since I was a child lead me to be very conscious and aware of how my body is functioning. This morning was one of the worst moments of physical pain. I should just take one step at a time with the sleep doctor instead of taking measures to see every specialist that could pertain with this issue. However, that is very hard to me. I don’t want to ever wake up in the pain I was this morning. Does anyone else suffer with health-related OCD? And if so, how do you find a sense of ease during moments like I expressed?

6 months ago I had a severe panic attack and it’s changed my life. Scared of 99% of foods, can’t take meds out of fear, been hospitalized a few times cause of blood sugar drops and other health scares due to poor eating. I’m constantly scanning my body finding any little thing that’s uncomfortable and then fixate and panic over the smallest things. Whether be a smell I’m unfamiliar with, a weird sensation in my arm literally anything freaks me out….. who has had success with exposure or has dealt with similar issues. I feel like I’m unintentionally slowly killing myself but I’m too scared for meds and therapy doesn’t seem to make much of a dent right now. Please share some success stories I need hope.
