What if my fears come on things like health isuess, like paranoia, to face my fear is to go test Everytime which is alot,and even tho I know sometimes am okay I still go with the idea uncontrollably, kindly advise

I started dealing with OCD when I became fixated on health issues, particularly the fear of contracting a life-threatening disease. If I experienced any kind of medical symptom, no matter how small, that even remotely hinted at something potentially fatal, it would drive me crazy, and I couldn’t stop obsessing over it. Then one day, I started having intrusive thoughts about accidentally hitting someone with my car, and I would end up driving in circles to check if I had. Eventually, I found myself overwhelmed by a flood of new obsessive thoughts and compulsions. One day, while I was at the park, a squirrel came near me, and for some reason, I felt like it attacked me. I Googled it and learned that squirrels could carry rabies, which spiraled me into a deep fear of rabies. I became consumed with the thought I received a bite from a squirrel, raccoon, or bat any time I’m in areas that trigger me. It started off only being inside then transferred to even being in my own home. This made me obsess over every physical sensation in my body, compulsively checking to make sure nothing was wrong. One compulsion that I hated the most would to be putting rubbing alcohol on me to make sure that I had no open wounds. Every day feels like I’m walking around in a fog of anxiety, constantly worrying that I won’t even make it to old age. Sometimes, it gets so overwhelming that I just want it all to end. It stresses me so bad at times to where my brain feels like I’ve been studying all day.

I don't know what to do anymore, the fear of psychosis and schizophrenia is so bad in so hyper aware of everything I hear and everything I see, I've always had eye floaters now I convince myself that it's really me hallucinating, I've always had tinnitus but now I'm convinced it means I'm going to go crazy soon, I can't sit in quiet because all I'm focusing on is what I'm hearing, and searching for any sounds I can't distinguish, when there's background noise I get so anxious if I think I heard something but im not sure I did or I'm just anxious, I'm terrified I'll start having delusions and sometimes my brain confuses some sounds for other sounds for example say I'm hyper focused and I breathe and my nose makes a whistling sound my mind interprets it as a scream and I freak out thinking I'm hallucinating only to focus closer and realize it's my own breathing, earlier I was so anxious that I couldnt tell if I had an intrusive thought or heard something, I don't know how to make it stop, I've been through this theme before I just forgot how hard it was I'm having a panic attack please help

Starting to think I have unresolved childhood trauma unfortunately. Health OCD is also driving my absolutely crazy but I'm too scared to go to my doctor. I worry about diabetes, illnesses, cancer, skin problems, etc. I just hope everything works out in the end. Right now I just can't do the things I love doing because I'm constantly worrying about everything. All of my worries are exacerbated and I just can't keep them away. They only come back.
