Always sick😔

I'm really upset that my milk dried up so fast when I went back to work. It seems like about a few weeks after it happened, Zoe has been sick. Wheezing, awfully congested and breathing funny, runny nose, and a bad cough. The doctor said she has bronchiolitis and gave her a nebulizer but it's not doing anything at all and she's been using it every other day for about a month. I'm gonna take her back to the doctor today because it's not getting any better; just worse. She woke up this morning with yellow mucuous in the corner of her eyes. I don't think it's pink eye, possibly mucous from her nasal area backed up. Idk. But this sucks. I wish I never stopped breastfeeding 😞
