Rest can support recovery without making you feel better immediately, and avoiding a difficult task can bring short-term relief. Either, both or neither description may fit; you do not have to earn rest.
The two paths invite reflection on needs and feelings before, during and after an activity. Note anything being postponed and what makes it hard, then choose a kind next move or rest first; uncertainty is allowed.
Optional and private. Avoidance is common and not a character flaw, and rest is not something you have to earn. If low energy or low mood lasts for weeks, a health professional can help you look at why.
