~ That actually does sound like a "black hole" — unfortunately. I hope you have a source of help. Do not let these feelings fester ‐ as they often become worse.I feel like what has happened with the cats has triggered an episode of depression, I’ve had it in the past. And I feel as though my coping mechanisms are deserting me. I’m by no means in a black hole that I can’t get out of but I’ve completely lost the ability to find joy in things.
You are not alone. The same has happened to me recently. Losing long-time friends unexpectedly, getting older, dealing with my own health and my cat family, etc.
Stay safe and sane ...
