I have had long bouts of depression since 1986. I noticed that when I was/am at my worst, I realised that I didn't have a 'song' in my head when I first woke up. It took a long time to realise this, but for myself, it is a profound indication of just where my mind is at
So, a serious question, do other people with major depressive disorders find the same?
I've written to a few medical research institutes over the last few years. I did get one reply from a university in Canada, expressing some interest in this. Thank you for reading.
