Living in the present can be a very good thing, because we deal with how we feel now, not yesterday or tomorrow. For instance, I realize that I am feeling antsy this afternoon: I did last night too. So I'm not saying that you should just forget how you felt yesterday; because if you feel the same way today, maybe your body is trying to tell you something. Therefore, take a couple of minutes to think about what is going on. What would help you in your current situation?
Sometimes, when one has Fibromyalgia or CFS, one's nerves seem to be on end for absolutely no reason you can pinpoint. However, I know what is bothering me. I have been spending too much time on the computer, blogging, or preparing something for a blog. I need to move my body, do some household tasks, step outside for a breath of fresh air, and take a break from the computer. I need to relax my mind: my mind is reeling from all the things I think I need to do.
