Same for me. I got COVID many times, mostly from work, but I think it broke something in me. I've always had some depression but this is neverending. I play things or watch things, but when my partner asks if I'm enjoying it usually the answer is something like, "I don't dislike it, and I'm not hating it, and I guess I'm having fun" but enjoy isn't something I've used to describe current activities, just past ones

I've wondered about "long covid" for a while, and also wondering about your last sentiment as well
