Constantly afraid of illness, what should I do?

I'm afraid of a serious illness and I've been to the doctor several times. So far, thankfully, my values ​​are fine, or rather, they only deviate slightly from the norm. However, I'm still worried that I have a chronic infection. Despite several tests, nothing has been detected. I understand if many people don't take it seriously. I'm also undergoing treatment. I've also been having strange, recurring symptoms recently. Most of them have thankfully disappeared, but I still have one symptom sometimes. But now I don't dare go to the doctor anymore because I'm afraid of getting on his nerves. I'm planning on going back for a check-up in two months, hoping that it will calm me down if my values ​​are okay, but I still find it difficult to wait any longer because I sometimes have strange symptoms. I suspect it might be a sore throat because my right throat is slightly swollen, at least that's how it feels when I touch it. I sometimes have a strange feeling in my throat and I have the impression that it's gotten a little stronger. I know that these situations aren't easy. because I worry a lot I don't understand why my psychotherapy isn't helping me I'm wondering what's going wrong in my therapy but I suspect the reason is that unfortunately solutions are hardly ever discussed at least when it comes to the topic of fear and worry because I feel more like I'm talking to a friend 🙁
