Is there an unspoken rule that when you turn 40 you are just automatically tired. Doesn't matter how much coffee or caffine you take in you simple feel tired. I struggle lately with it I feel in a fog like my own body is to much effort to move. I make it through the days and get every thing done but it feels like that is all muscle memory or something because when I stop all I can seem to think is I just want to sit here please do not talk to me or ask to touch me or ask me to move. 

I am use to that from my years in a depression and all but this is different I am not depressed in fact I am happy and so content and blessed and yet I have no energy to even think.

What the fuck is this and how do I make it stop?
