When I am depressed it takes enormous energy for me to deal with people. Meeting new people when it is incumbent upon me to make a good impression is particularly exhausting. I had to leave the house(!) and be articulate and positive and intelligent (pertinent: my formal schooling was in artificial intelligence) at thanksgiving with three friends-of-a-friend whom I had never met and felt I had to impress, and, although I suspect that I was largely successful in my deception, the interaction was so tiring and stressful for me that two days later I want to pop benzodiazepines from the mere memory of it. That's post-conversation anxiety, which sounds like a new low.
