No you are definitely not nuts, I'm exactly the same, I have been for months now. Extremely sad & tired.
To be honest I was wondering if it was just me as well.
I also find it tireing trying to hide it from everybody.
All I want to do is lock the doors, draw the blinds & take the phone off the hook. But I know that people would soon be knocking on the door & asking questions.
This is all just to hard to explain to "healthy" people.
So we put on our happy face & solder on.
Hope things pick up for both of us soon.
