How did you sleep?
I am glad you got Valium. I think once you start eating and taking the med regularly you will feel better.
I was told by my old p-doc back East, when I felt or thought I was going to have a anxiety/panic attack, he said take a (I forgot what benzo it was) and put it under your tongue and let it dissolve, it works very fast.
I did it and it did work ASAP........Take care, eat, get rest, feel better.
