I can relate to all you've described! My question for you is, do you think that it has anything to do with the time of the year? Ever since we turned the clocks back one hour for daylight savings time, I've been feeling sort of "draggy". Meaning, I am just dragging my tail around to get things done!
My impression of myself, is realizing that it is darker earlier, and when the daylight goes, it takes my energy with it. I am going to bed sooner, sleeping longer and am less motivated to work when the weather is cold and I feel a bit holed up in the house. (I am so sensitive to the cold, I layer like crazy when I go outside!)
Also, with the holidays, and all of the extra work that it brings in decorating, shopping, meal preps, cookie baking, work and social parties to attend, these tend to compete for even more time in your life, on top of all of the usual obligations. Juggling all of this is stressful and tiring.
I laugh at myself, saying that at this time of the year, I wish I were a hibernating animal! LOL! I want to eat to fill up my fat storage, sleep through the cold winter months snuggled in a warm, safe place and avoid all of the crowds and noise!
What I really end up doing though, is pacing myself. I am no longer concerned about how others feel when I turn down a holiday party; I make less complicated meals; I decorate less; and, I take care of my soul more. I am listening to the holiday music that I love, and watching the holiday movies that I love and am learning to feel less guilty when I take my Power Naps on the occasional afternoon.
Oh, and like Umar, I also make a list for the week. If I even get a few things crossed off, it is satisfying. I've learned to stop expecting perfection in myself, and am OK with making any progress that I can.
I hope this helps!
