From Wikipedia: Chronic fatigue syndrome (CFS) is a medical condition characterized by long-term fatigue and other symptoms that limit a person's ability to carry out ordinary daily activities. Quality of life of persons with CFS can be compromised.
And some clever person came up with "The Spoon Theory". This analyzes your energy (spoons) and the tasks you have and then take spoons away for each task.
It's not my analogy but it could work in other ways. For instance, take today; I wanted to cook dinner for David and I, I wanted to take a shower and then Kristin asked me to watch the kids while she goes to the doctor. For me that is 3 major suckers of energy. When I woke this morning I thought I just had the two...the shower and dinner. I'm not complaining, I'm explaining. A lot of days that I cook, we have our main meal at lunch time, around 1 pm. This morning I woke up with very little energy, I guess I didn't sleep well. Anyway, I went over with Cali to get her on the bus. When I got back home I read for a while and then laid down for a while. I got up around noonish and started dinner. I had an easy meal of hamburger, gravy and noodles. Easy peasy, right? One thing down, a couple to go. However, I know I won't have the energy to shower AND watch the kids so I've postponed the shower to tomorrow, after all, tomorrow is another day. I'm already borrowing time from tomorrow.
Does any of this make sense to you? I'm irritate that I'm exhausted. I know this isn't well written, my brain is tired too.
