I had a really smart instructor once that was scolding me over a grade in a test. I told her that I only failed by 2 points (I got a 68). She said ‘no, you failed by 32 points,’ and I’ll be damned if that hasn’t stuck with me for 24 years.

You didn’t lose it over a sandwich. You had a string of crappy things where you dammed up your emotions, then the sandwich broke the floodgates.

Big hugs OP. I’m really glad your friend was there to catch you when you fell.
