Real talk: When does it get less overwhelming?

My son is 6 weeks old and I'm not gonna lie, the constant anxiety is exhausting. Is he eating enough? Why is he crying? Is that rash normal? Should we call the pediatrician? He spit up a little more than usual today and I nearly had a panic attack. I'm a reasonably competent adult in other areas of my life but this has me completely unhinged. My wife keeps saying it'll feel more natural but right now I feel like I have no idea what I'm doing and I'm one mistake away from messing him up forever.
