This might not be the place but I need to vent

My daughter (born 12 weeks early) is 5 months old today (2.5 months old if she was born on time) and she has come down with the worst cold. Now this wouldn’t be a problem EXCEPT she has chronic lung disease and her oxygen keeps dropping. Her pulmonologist told me she’s fine and just sick and not to worry even though her oxygen levels are hanging out at 85 instead of her usual 95, they have me administering around the clock albuterol through a nebulizer (of course the medicine must goes everywhere since she’s an infant and I know I’m breathing it in). She has to get her 80th chest x Ray tomorrow to make sure her scarred lungs aren’t developing pneumonia. And I have to give her a weeks worth of heavy oral steroids to reduce her lung inflammation. I feel so bad for her, it literally breaks my heart. I can’t sleep and I’m so exhausted and the nausea has started to kick in (I’m 6 weeks pregnant). I’m so upset I won’t be able to comfort her during her x Ray like I have all the other times. Im super hormonal and I don’t want her to have to be readmitted to the hospital. The nicu strikes am insane amount of fear into you about your preemie getting sick. They kept telling me any sickness and she will probably need the ventilator again her lungs are not healthy. I’m sorry I just needed to vent and I’m so worried about my baby 😭 I’m lucky she figured out how to mouth breathe because that’s what’s keeping her at home with me right now.
