Anxious night (nothing to do with Harley)

I can't sleep tonight. I got up at about 1:30am and let Harley out. He went out and did his business and came right back in. I think he was cold. There's a cold front moving in and you can sure feel it tonight. I would have liked to keep Harley up with me but I don't want him to get used to getting up every night. While he's a puppy I'll still let him out during the night but once he's able to hold it overnight, he'll be sleeping the night through even if I don't. I'm not sure what's going on with me tonight. I was cold even though I had a blanket on and I kept feeling anxiety that woke me up. It's a real weird feeling that I could do without. I guess I should head back to bed and try to get back to sleep. I hope Harley is able to get back to sleep too.
