On a bad mental health day, you shouldn't hold yourself to the same level you do on a good day.
If you’re human, it’s simply impossible to go through life with no bad mental health days. Whether coping with a negative experience, dealing with a life change or just waking up in a low mood, not feeling 100% mentally or emotionally is just a part of life.
Exactly what a bad mental health day looks like will vary from person to person — some folks may feel scattered or stressed while others feel low energy and tired.
