Am I an idiot for also texting my coworker on ambulance groupchat?

Im admin assistant at hospital and our duty is 6am-6pm/6pm-6am Im on night duty and its aready 6 am and my coworker who is gonna change me for next duty is still not appearing. I know Dea is the one whos gonna be on next duty but she's not here. Its already past 6:38 am usually they are here before 6 because 6 is the start of duty. I texted our groupchat the info groupchat and another info groupchat which group that included our boss and I also texted the ambulance drivers groupchat that included us as well because as admin assistant on our duty we text the ambu drivers there if we have conduction. I texted the ambu I said "Info whos the next duty next to me? Up until now no one is showing. And Im so stressed what if no one showed up? What if my duty will be straight 24 hours because no one showed up I can't go out until no one is showing to work on next duty. Im so tense. Later Jee mentioned me on groupchat that she understands I want to go home but she doesn't understand why the need of me to text our issue on ambulance drivers? Like she sounded mad at me Just to be clear we are also part of ambu driver groupchat because its our part of our job to message the ambu driver whenver there's conduction. On 6 past am there's calling that there's ambulance conduction and Im so tensed what if no one showed up and Im already sleepy from my last duty. I texted Jee and I said sorry and I apologized I told her I just panicked I thought no one would show up. Jee said she will be a replacement for Dea today and she will be here before 8 am. She arrived at 7:56 am. And later on my boss mentioned me on groupchat saying she's sorry for me because I went home late and that Dea should have told earlier she won't coming today so Jea get prepared early to replace her. Im asking am I wrong for texting the ambulance drivers asking the next duty?
