I also go through spells of that. Absolutely nothing I can think of to do sounds appealing. And it’s stuff I used to enjoy. For instance, gardening. I used to love it, but the thought of going out and getting my garden ready for spring sounds like more of a chore. Speaking of chores, anhedonia also makes it more difficult for me to take care of things that HAVE to be taken care of (bill paying, house cleaning, going to the grocery store). I find it helps if I make a list of those things and scratch them off as I get them done). I don’t know where my enthusiasm went, but I wish it would come back!
