Bad day go AWAY!!!

I had a bad night. I was thinking about my anxiety attack yesterday and couldn't fall asleep. I was laying in bed exhausted, but my mind was going 100 miles an hour.
I was supposed to help my mom today with getting her taxes ready for the CPA. I had to call her and tell her I was going to be at least an hour late because I couldn't sleep last night. I could tell that she was mad, but she just said okay see you then.
I fell back asleep and woke up to my alarm. I got ready as usual to go to my moms. Got my dog ready and gathered her things for her trip to her grandmothers house. My dog also has anxiety problems. She loves going on trips, but when I leave her for any length of time she goes crazy.
My husband has stayed home with her a few times while I had to go out. He would call her to come in the other room with him and she would sit on the back of the couch looking out the window and not move or eat until I got back home.
Anyway, I am getting off subject. I got Shelby's (my dog's) things gathered up to carry down to the garage and opened the door to the garage. My car door was wide open. I stood there shaking my head and feeling so stupid. I attempted to get the car to start and of course the battery was dead.
I was completely dreading the phone call to my mom. She was already upset that I needed an extra hour of sleep. Now I can't make it at all. My car is stuck in the garage. I called my mom and explained my battery was dead.
She was upset, but understood. I came back upstairs and immediately started worrying that if the house caught on fire I would loose my car.  My anxiety was soaring. I started cleaning and tried to think about other things. I slowly started to realize that the house hasn't caught fire yet and that the likely hood of that happening is not very likely.
My anxiety gradually got lower and I now feel stupid for even letting that enter my head.
