Note that "mental health" doesn't just refer to chemical inbalances or miswiring or whatever else - in a more general sense, it refers to literally what it says, the health of your mind. If you're suffering from burnout or exhaustion, that is not a healthy state to be in. (I'll note that the DSM-V apparently does not contain burnout because it's problematically close to depressive disorders, and exhaustion is a symptom of a lot of things.) If you can help yourself, that's awesome, but for a lot of people, a professional who has experience helping people in dealing with these problems might be able to help them too.
