Problems focusing

I'm having one of those days where I just can't focus.

Part of it is worrying about money. The first week of January was busy for me, but since then it has tapered off significantly, which has me concerned.

Part of it is having too many little things to do. I feel like my focus is divided between eight million different little things, which makes it hard to concentrate on the client project that I'm supposed to be doing right now.

Part of it is the weather. It has been unseasonably warm for the past week, and it's distracting to be sitting at home today when I'd much rather be out at the barn.

And part of it, I'm pretty sure, is my physical condition this week. My sleep schedule has been far more irregular than usual, and on top of that I've been dealing with some significantly low blood sugars the past two days.

Of course, feeling like I'm not accomplishing anything only makes me feel worse. I always feel terribly guilty when I get stuck like this. So I'm curious — do any of my fellow freelance writers ever experience similar days? And how do you get through them when you do?
