I‘m not going into details here, just need some advice for today. 

Last week I had an appointment with nitrous oxide. Despite that, I was still shaking and in tears almost the whole time. Sadly, something minor was overlooked and has to be spontaneously fixed today. It won’t involve pain or invasive stuff. Still, Even just writing this has me in tears and shaking again. I have no clue how to be able to get this very short and easy procedure done today. 

I‘m already looking into therapy, but I need something, that I can be doing today, so I can just survive this appointment today. Last week I tried box breathing, but it was not much help. It takes minutes to calm down a bit and anxiety spikes again the moment anything is done, even just opening my mouth.
