So I have taken a few days of the PhD stuff, a day or two off work.
Why?
The times when I have been up and about, I have been preoccupied, and forgetful.
I have got bugger all done with the PhD.
Twice this week, I forgot I had patients.
Twice this week, I have forgotten where I parked my car and spent nearly an hour looking for it. While looking for it, I just wanted to lay down on the ground and go into the foetal position. Sometimes I stop, look around, scratch my head.
So. Much. NOISE. Can’t focus. So I forget. And all I want to do is lie in bed with the doona over my head, and I have done just that.
I have been fighting all year to feel good about myself despite some major things happening. I thought that I was getting the hang of it.
Why, why did I lose that feeling? Nothing really has changed.
Here I am, about to find out.
Demons, dancing, doctorates, debauchery. 
Enjoy the time under the doona. You don’t have to be on top of things all the time and you do have to allow yourself some time to adjust to a good mental state. Don’t let anyone make you feel like you have to apologise for it.
