I just realized, all the past week I was interacting with a lot of different people, from family to strangers. It was great fun, but I am officially wiped. I have no emotional energy left to interact with enjoyment. I forget about this when I "binge" on social interaction so to speak, since I'm not around people too often. I get on a high being with them but then I come crashing down, and I need to let myself recoup before trying to be a pleasant and social human being again.
It's such a relief to realize this. I thought I was going mad feeling this extreme aversion to speak with anyone.
