Flu with a new baby

I’m at urgent care right now getting a flu test. I feel so bad. Fever, chills, and trouble breathing. Not sure what it is, but I guess most likely flu since I was around someone with it a few days ago. What do I do!? My daughter is 2 months old, and already has breathing issues. How do I keep her from getting it? Can I still breastfeed!? I’m so distraught and worried about her.
