I'm so sorry you're having one of those days. They're nooooooo fun.
I read something around the holidays and have been using it since and it helps me. The suggestion was if you're getting overwhelmed and stressed by holiday activities to get outside, even for a few minutes, and that the fresh air, scenery, etc., would help lower your anxiety. I thought, "Right..." but the next time i got stressed I bundled up the little guy, put him in his stroller, and we took a walk around the block.
We were gone under 10 minutes, but when we got back and came into the house I truly was less stressed and could look at things with a fresh outlook. So since that day I've done the same about 3 times, and it always works. Trust me, the mess is still there, lol, but I'm able to say, "oh, what the heck!" and move forward. Something about removing myself from the situation and getting fresh air and a little exercise helps me see the world isn't going to come to an end because there's yogurt and Cheerios on the floor that was mopped 2 hours earlier, and my blood pressure comes down.
I hope your day improves : )
