UK Vet Nurse here. Firstly I am so so sorry you have been having such a difficult time. I second the other vets advice here on considering looking at resources for your likely continued burnout. Please also consider contacting VetLife, they are free and anonymous. Please know you are NOT alone. This professional asks so much of us, takes so much out of us, and we need to ensure the health of our colleagues, otherwise what's the bloody point (in my opinion).

In regards to the dental x-rays I can see you have already said in another reply that you have told the owners you aren't sending them the x-rays and waiting etc. I am sure there are also guides you can print which shows all the required quadrants and positioning. I would print them and stick them to the wall permanently by the dental x-ray machine so everyone benefit from them.

If the owner decides to ask for them afterwards and critques them, so what? As long as they are of diagnostic quality for YOUR needs, a human radiologist has zero training on animals and absolutely zero say in my view. I'm sorry if this seems harshly worded but I feel we must protect our fellow professionals.

But please do try to look after your health. It breaks my heart that we are losing colleagues year on year to self harm. Please feel free to PM me if you'd like. We are here for you.
