Less than 2 months to EDD & freaking out

Hi all… suddenly have a panic attack while showering. Was so so worried about my baby’s health and wondering how I should deal with if baby turned out to be unhealthy. I even linked to my cousin who have some mental disability which caused him to not have control of his limbs and mentality. His fingers are always cramped up and showing twist. Coincidentally, during my baby’s 16th week ultrasound, we also captured a shot of her showing a somewhat twist sign which I initially thought was so cute and rare but now, I’m just freaking out thinking what if she has the same condition as him. Helpppp I’m so worried😩😩😩😩
