Due to work but baby is sick!!!

Hey all ! My girl is one years old, having not long returned back to work. What would you all do? My LO has been ill for a few weeks now, been to doc who said everything seems fine , ears a little red. However last few days she has been so upset and irritable, bad sleep & completely off her solid foods, water and cows milk. I am still breastfeeding and this has obviously increased as all she will take is that!!! I’m due to go to work in 4 hours - am I being stupid for so badly wanting to stay home with her? I want to take her to the doctors and I don’t feel it’s fair leaving her with other people when deep down I know it’s me she wants. Plus I haven’t slept!! And will probably get about 2 hours if she doesn’t wake up for the 9th time tonight!! I feel guilty and that I would be judged for calling in and not going to work. Please help!! Am I being unreasonable??
