Boy Sundog, I can relate. Your description is right on for me too...
I guess I would add that on really bad days I have the "broken heart" feeling. I have this weight in my chest that I just can't get rid of and simply always want to break down in tears.
But on days like today I just feel tired.
Not tired like I need to sleep and will wake up well rested and ready to face the day. I wish for that. It is a different kind of tired. Sort of... tired and very confused. Listless. The way I get by is to simply have no extraneous movements.
The furthest I have been able to go today is doing housework.
I am trying to simply be proud of that.
I meant to get out and look for work but today I have given up on it again.
It's rainy and horrible outside and I know I will feel worse if I go out there...
So taking care of the house is it for me.
