Acedia is an emotion that means you feel tired or lazy. It's like when you just don't want to do anything, or when you just don't have enough energy to get anything done. It can make it hard to keep up with things like going to school or doing chores around the house. You might start to feel like things are too hard, and nothing is worth doing anymore. It's like you're stuck in a rut and can't find a way out.
