Hi Bpancakes and welcome :)
Do you nap during the day? If you are able to I would definitely take advantage of that. The dishes can wait, so can the laundry. A well rested mommy is much more important and a better mommy by far!
Worrying, as much as it comes so easily to some of us, is only going to make you feel worse as Lynnwood has said. Try to take a deep breath when these thoughts overwhelm you.
The way I rationalized during my most worrisome times during awaiting diagnosis was to remind myself that the worse things are the clearer and easier they are to diagnose (most times). It is early days, things are just starting to show up in bloodwork. That generally means no significant damage has been done or you would be in the hospital with dialysis, having your thyroid removed etc. And many people with autoimmune disease never have organ involvement. The fact that most of your results came back ok means that your body is doing ok despite the challenges that you may be experiencing due to an autoimmune disease making you feel like a sack of crap. Just remember to keep trying to get some answers and persevere. Don't let doctors brush you off.
I hope that made sense and didn't come across wrong.
I'm not trying to minimize what you are going through. I went through the exact same thing and worried myself sick. It took a while but my rheumy has somewhat put two and two together and I am getting treatment. Treatment and prevention is what is important at this stage for me. A definitive label, not so much in my experience.
Hang in there and take good care of yourself. Keep coming back with your fears, it's not a bother. A good many of us have been on the same roller coaster ride.
