My health anxiety

So ever since I can remember, I’ve been very alert to any health concerns that I could be having. When Covid hit last year, that fear only grew stronger. I ended up measuring my bodily functions multiple times every day, which in turn fed my anxiety up until the point where I am now. I have many symptoms that worry me, but they are most likely just caused by my anxiety. Even though i go to therapy, I always doubt myself when i start getting certain symptoms again. My biggest fear has always been to have some sort of degenerative/nervous system disease, and the symptoms that anxiety gives me, just make this fear worse. I experience dizziness, headaches, uncontrollable tension, weird muscle twitches, eye floaters, etc. All i want to hear is just people who’ve gone through the same things and can assure me that it’s all actually just the anxiety, as sometimes I have a hard time believing myself. My health anxiety has caused me to go through waves of depression, and I’m really feeling like it’s been enough.
