Really sorry to hear about you and Katie having troubles Dave. You've always been one of the users here that I always look forward to seeing post, and I figured that the loss of Bailey and Cleo was weighing heavily on you, but hoped that was all. Unfortunately, the most I can do is send well wishes to you and your family with the sincere hope that things start to normalize for you guys soon.
I've struggled with making myself take care of tasks myself at times. Dealing with what I would consider very minor mental health issues, and a two year old who's busy being a two year old lol, sometimes I just don't feel like coming in the reptile room and cleaning. I've never let it get out of control, but my weekly cleaning day will roll around and me having had a rough week just don't want to do it. Those little humps are rare, but they were happening enough to the point I felt I had maybe taken on too much animal-wise. I've actually spoken to a close friend multiple times who breeds hognose snakes and discussed re-homing my two, but always backed down from that idea once the moment passes.
Point is, you're not alone. Stuff comes up and sometimes we have to, not lower our standards, but understand that we have to prioritize other things. I have no doubt that you're still taking excellent care of your animals even while taking a step back to take care of your human family. Just be sure you're making some time for yourself too, which I know is hard considering how focused you are on getting Katie better and taking care of things around the house, but just don't forget that you need some time for your own physical and mental health as well.
Anyway! It's good to hear from you, here if you need a chat, and wishing you and yours the best.
