In my experience, emotional pain is as much a signal as physical pain - great you are paying attention. Research shows that sleep is an important factor in mood and overall productivity - so don't skimp on that. It also shows that friendship and social interaction is important to mood - in fact, talking about issues/being heard prevents ruminating. And, taking breaks is very important for creativity. Your emotions may be messaging a need to be a bit nicer to yourself. We all relate - hope that helps.
