I have reached the point where I know that fatigue like this just happens. It has been very very difficult to accept it, but I have to put myself in a mindset where I can "just go with it". If it means a ahile in bed then so be it. Sometimes I can read, sometimes I can just listen to music, sometimes I can't stand even having my eyes open or to hear any kind of noise. The more I push myself, the worse the fatigue will get. Then the only thing I can do is rest - and that rest will happen one way or another. No, you are not a downer.... this is what we live with day in and day out. Perhaps the changing of the season is having an effect on you too. But probably the best thing for you is to rest.
