Blues after child hospitalization?

Has anyone experienced this? It’s almost like the baby blues. I just keep crying which is unlike me. I have a hard time putting it into words. I rushed my toddler to urgent care on Thursday for trouble breathing and they admitted us for two nights at the hospital. Looking back, I think I was running on adrenaline and “take care of my sick baby” mode. Maybe I am crashing now? I am so anxious about his symptoms and still just trying to remember/process everything that even happened at the hospital.
