I feel totally derailed

I managed to move a couple of bookshelves, get those back together, put my clothes in the closet rather than on the drying rack, and then I got a phone call and now I feel like there's no point to doing anything I wanted to today, because I'll feel rushed and not enjoy it. I know that's mainly my psyche, but that's how I feel. I've spent the last half hour trying to get some food in me (I don't have much appetite, actually) and then trying to jump-start back into what I was doing, without success. I think I'm just going to take a shower and go from there.
