Firstly I'm glad your daughter is home.
Secondly, I've (luckily) not been in your position. The closest I've been is we got a 2am knock on the door from a police officer "your son has been involved in an RTA", despite being almost outside a general hospital, he was taken to a head trauma unit further away. Things were looking very serious.
I went into coping mode, I was completely calm and refused the offer of a lift to the hospital and calmly and safely drove my husband and other son to the hospital.
My husband went to pieces couldn't drive, could hardly get dressed etc.
When we got there he was having a scan, the paramedic crew had stayed for us to arrive. They explained everything that they knew, that they were not first on scene but they were used because they had the specialist equipment needed to transfer our son. They explained he had been able to communicate, what he said and what had been done on route to the hospital.
I can recall word for word what was said, I took it all in, my husband cannot even remember the conversation.
Thankfully things were fine and he very luckily (police couldn't believe it!) fully recovered.
When relating the events that night the vast majority of people came out and said "I don't know how you drove, listened to paramedics and doctors etc, I would've been to upset, frightened". I too felt judged, I can assure you I was every bit as scared, frightened and terrified as any other mother. My coping strategies are different and I needed to know and understand what was going on, in case decisions needed to be made.
You coped when your baby was unwell as best you could, being vocal, being there 100% of the time you were unable to do, that's no criticism and merely you coping.
I hope you can let this go, it's unimportant and just taking up headspace.
Good luck
