When isolating and you receive an email
I read them, but mostly do not react / react only to people that do not exhaust me more.
ETA: I also respond to emergencies, but they are more like happy news: something superpresent, drag me out of the past and present blend I am isolating FOR, canceling that need to isolate for a while and superseding the head funk I am in.
Unless I am also badly depressed or injured and depressed because of it, at the time, then it is a lot of headbang, bite me, but I will find who else to get on it.
