I just posted a similar thread. I totally understand your situation, I have been there and am there many days. I don’t have any advice as I am in the same place but don’t succumb to the voice in your head. Can you talk to your boss and ask them to help you find a solution to the volume of work? I will say when I have done this with my current boss it has been helpful. That said my day yesterday was highly stressful and my voice said “wine wine wine” but I didn’t do it. I did drink a lot of herbal tea...
I hope it gets better for you. I get it!! I have started drinking at 2 previously when under extreme stress.
