I know how you feel
I felt drawn to your comment. I had same trouble to motive myself, and spend hours almost catatonic. I've read that the reason for this is that we are low in noradrenaline. I've been taking Theramood, Theanine (you can further information at their site ) for the last week and I think it is helping - one tablet - you have to take it on an empty stomach. It helps your body make noradrenaline.

You could try that and see how you feel.
