Sounds like me... But then sometimes thinking in bed leads to new ideas. Before sleeping, telling yourself to solve problems may work. I didn't even know about this, but apparently your subconscious can be instructed to go to work this way and give you results the next day or soon thereafter. There's a whole science to it.

Nonetheless, I know the feeling of having no motivation and wishing just to stay in bed all day. Sometimes the pressure is overwhelming. The current work-from-home situation only worsens this, since no one is even checking up on me.
