Grief is Exhausting

People often wonder why grief is physically exhausting. We often miss the fact that emotions aren’t just feelings, they’re biochemical reactions. Grief is induced by and induces a lot of stress chemicals (like cortisol) and you don’t get enough of the happy chemicals and endorphins. Your body doesn’t function well in this state.

Then there's also the fact that your brain is very energy-hungry, so any time you use it a lot, you will feel tired, e.g. studying, or jobs that require frequent decision-making. The simple act of thinking about the person you miss all the time uses up a lot of energy. On top of that, people who are grieving often don't replenish the energy used because they are sleeping and eating less.
