Feeling down

I feel like a bad mother. Like nothing I do is ever right. My child is always sick. Plus she's a premie. Just took her to the doctors and she has an ear infection in both of her ears. Followed by pink eye in both of her eyes. With a fever and oh yeah a cold! My child is always constantly sick. And I'm now sitting in my car crying my eyes out. Because no more what she always gets sick. She has RSV. Than she had Corona! Than after that she got congested for four months. Than when it all went away and she was okay for two months and now this. I just feel like she can't catch a break.
