Seasonal brain fog.

I've noticed that I seem to have a yearly cycle in terms of mental states. My mind seems to go through regular phases that correlate with the seasons. Each fall I find my mind getting foggy. I find it more difficult to think and speak clearly. It is not that it is a symptom of seasonal depression, because I really enjoy the fall and find that I am generally happier during this time. But a haze seems to cover my mind. Perhaps it is the lack of sunlight. Perhaps it is just part of a natural rhythm my body follows and it happens to occur as the days get shorter. Perhaps something else entirely.
I've begun numerous blog entries that I quite after only a few lines because I have trouble clearly thinking about and articulating what I have in mind.

I seem to experience this every year around the same time and it usually lasts a couple months.

I make a great deal of effort to communicate clearly. Clear communication is something I value a great deal. When the fog descends on my brain I can sometimes struggle with expressing even simple ideas. Because clear thinking and communication something important to me, it can be frustrating when it becomes a struggle. Even now as I am writing this I am struggling to find the correct words to explain myself and feel i am falling short. Hopefully my seasonal brain fog doesn't last too long this year or I can figure a way out of it.
