I think most of experience anxiety of some sort or another during die off. I’ve never had it exactly like that, but I can relate. Dont let it scare you, just be smart about it if it gets any worse or becomes a problem. Maybe try backing off the antifungals a little if its more than you can handle. Its not a race to the finish line, the goal is just to get there and in one piece.
What are you using to help with die off?
