1st time being sick

I had to take my baby to the ER because she was obviously sick. Wheezing a bit, coughing, congested... She just seemed so miserable and it broke my heart.... She has covid and a mild case of pnemonia. I legitimately started crying when they told me the diagnosis... I felt responsible and wish that I could be the one who's sick instead of her.... But they gave her amoxicillin and Tylenol (she keeps gagging on the Tylenol). How do you guys deal with the mom guilt?

The amoxicillin is already starting to help her... But I still feel guilty
