Anxious day

Friday at work actually went smoothly., My manager leaving early certainly helped, as I just want to come in, do my job without hearing from management, and go home. Yet from yesterday afternoon until now I've been in an anxious state. Did not sleep well either. One way I can tell I'm noticeably anxious or sick is that my cats lie down on top of me when I'm in bed, which they don't do when I'm not. It's a vague work anxiety. I did not sleep well last night. May take a nap before work.
