Constant Unhealthy Worrying about baby 24-7!

I’m 26 + 3 days and I swear I literally can’t sleep at night. I didn’t have this my first pregnancy. I think stress plays a factor. Worrying 24-7 about my baby. Baby has had multiple scans, tests, anatomy etc. & doctors all say he is fine. I recently had to have surgery to remove a kidney stone, so that was scary. At the beginning of my pregnancy NIPT results should risk of trisomy 13, re-blood draw and it was a false positive. All I have done this whole pregnancy so far is worry, it’s unhealthy. I see a therapist, helps some, but still worry daily. I don’t know what to do about this constant feeling/ fear that he won’t be healthy or something will go wrong. My daughter now 5 is healthy and came right on time and my whole pregnancy with her was glowing and worry free.Does anyone else worry daily about their baby, like constant unhealthy worrying? Any advice? 🙏🏻
