Off

I've been feeling kinda off lately. Not angry, not depressed, just...off. I know I am usually better at articulating things but I can't seem to put my finger on this. I don't know if it's a cyclical thing, since I seem to feel odd at certain times of the year (I haven't pinpointed if it's every month). It's annoying.

I feel like nothing really is fitting the way it should. Not at work, not at home, not alone even. I feel overworked when talking about what I am doing now, except what I am doing now is only a little more than half of what I used to do. I feel out of sync when I get home, like I am not doing everything I should be doing, like the house is disorganized and I don't see my kids or hubby, and the rest of the time I feel like I'm invisible because I spend so many hours away from home. When I'm alone, my mind wanders to places known and unknown but not very useful. It's indescribable at the moment.
Is it restlessness? it is dissatisfaction? Is it psychosis?
