I jus have way too much on my plate day-to-day.
What kind of responsibilities did you have?
It would be too long to explain.
Sometimes we do take on more than what we can handle, and it is okay to take a break. Then you can do the what you need to do with a clear mind.
When I sleep my mind often wanders to what I need to tackle, instead of focusing on getting the best possible sleep.
Then you really need to take a break. Burning yourself out does you no good.
