Personally I just feel exhausted all the time.
I don't know why. I just do. Chalk it up to old age?
I have a routine of household chores I typically follow each day. Sometimes, accomplishing it feels little short of climbing a mountain.
But I just make myself keep going. My penchant for passive suicidal thinking spikes during these periods.
In my case I don't know as there is anything I can do about any of it. The chores have to be done. And I'm not going to get any younger.
So I just keep doing what I know I have to do...
