Hi Wednesday, I have been through periods where I have been entirely unmotivated. I have to say it's mainly due to feeling depressed. Now I don't feel I struggle with depression but I do and have always gone through times where I just feel so blue and so unmotivated. I'm inclined to believe that it has something to do with hormones or some cycle of my brain and the neurotransmitters being (or not being) released. As I've gotten older I've learned to just keep my butt moving even if I really don't want to or it just plain sucks. If I can keep myself in gear it seems the next bout of saddness is easier to deal with. I have theory of learned behavior; that I'm training my brain to push through the sorrow and lack of motivation. Keep in mind I've been experiencing this since I was a child. My mother says that when I was a baby I would have days where I seemed to be blue so for me it's gotta be internal.
Now when I was flared up I grew very tired and then feelings of hopelessness started to sink in. I feel that's different; there's a external factor.
How's your diet? Have you had blood work done recently? Maybe you're anemic or perhaps there's a B-12 defiency. It very well could be something like that. Try being aware and honest with yourself to determine if it's your body or your mind.
We all need days where we just do nothing. Most of us derserve days like that. But if you're unhappy with what's going on take the time to get to the bottom of it. It might take a while and more days of feeling unmotivated but eventually you'll figure it out.
